00:01:22is given so that the force is the value minus d y d r or x or y. If it is the value of u

00:01:34which is in the form of r. The value of u is the distance of r. The value of u is the

00:01:41respect to r. The force is the work energy power chapter. This is why the work is

00:01:47Question.

00:02:06If a particle

00:02:08if a particle having

00:02:18potential energy

00:02:23u equals to 2

00:02:31u equals to a r square

00:02:33with

00:02:36force acting on it

00:02:39with force acting on it

00:02:47always perpendicular to its motion

00:03:18करवा रहा होगा और कौन सा फोर सर्कुलर मोशन करवाता है मतलब जो फोर्स आएगा उस सेंट्रिपिटल के बराबर है

00:03:24if all the assumptions of bore model

00:03:28if all the assumptions of all the assumptions of bore model

00:03:33are valid

00:03:36all the assumptions of bore model are valid

00:03:43then

00:03:48radius of

00:03:53nth orbit of particle

00:04:01will depend on n

00:04:10according to

00:04:15will depend on n according to

00:04:19बतलब क्योशन में क्या पूछा जा रहा है

00:04:21radius जो है वो n की कितनी power पर depend कर रहा है

00:04:27यह है क्योशन यहीं तो है अच्छा अगर हमारे पास में यह

00:04:32यहां से जो फोर्स आएगा वो बाइनस में डियू अरे किसका फंक्षन है आर का आर का रका रका रके रेस्ट में करेंगे तो फोर्स की वैल्यू क्या जाएगी माइनस में तो यहां

00:04:41यहां से जो फोर्स का मıyorsun डियू अरे किसका का टाइगा तो आड का पर्स में करेंगे माइनस में तुए रा यह

00:05:03see

00:05:10yeah

00:05:15say it to a are key value kiss cover ever mv square by our appellation yeah go to make

00:05:22a bowl at us and triple cake equation but now after a time where you send a video

00:05:27equation key q1 q2 upon our square i have a wopper are square out of the last class

00:05:33migration kia tha us where we force k by r i have a choice while i may force the

00:05:39a

00:06:06we hate value he who and by our can enforcement it's professional my weak value and by our

00:06:15uate the fix say they are to be a weak will be here of the equation one US

00:06:23history in Canada II am RV kids are a personal TV square people are in square by our square

00:06:30This is 2A R.

00:06:35This is R cube and this is R.

00:06:37What is R?

00:06:38R is 4 proportional to N.

00:06:41So, R is 1 by 2.

00:06:44So, our answer is R.

00:06:47R is 1 by 2.

00:06:50Do you understand?

00:06:51I have said before that,

00:06:53that there are two equations of work.

00:06:54There is a centripetal and a mvr.

00:06:57As well, the first question is no problem.

00:07:00In the beginning, the first question is R.

00:07:04So, R cancels are V constant.

00:07:07So, if R constant is normalized,

00:07:08then R is proportional.

00:07:12So, following this,

00:07:13V and R are R.

00:07:14So, here we will try to take V.

00:07:17Or do R and R equal?

00:07:19If this equation is solved,

00:07:20then we will do this.

00:07:23So, we will try to take V.

00:07:25So, this is R to value.

00:07:26I will ask you, if I have asked you, how do I have to see the value of V by N?

00:07:33If I have to see the value of V by N, I will see what I have to see.

00:07:40If I have to see the value of V by R equals to NH upon 2π.

00:07:45If I have to see the value of V by R, I will see the value of V by R.

00:07:53I will see it as a non-market value of V by R.

00:07:58a proposal so yeah so you want to be key value because you're a and keep power half

00:08:04care propose you boy is what I look like very hypothetical to me I look like a time period

00:08:10nicals of today again must put it at a new time period in the college with time period

00:08:15and take a step and go to put a time period key value to buy your phone maybe a chair

00:08:20here is value value and keep power one by two are you be and keep power one by two

00:08:25yeah time period constant but the point is that the same time

00:08:31it is all right there is a situation where the other is a data

00:08:35I don't know

00:09:05I am R square equals to n to R value n power half.

00:09:10How can we solve that?

00:09:11The other proportionality is going on.

00:15:09And,

00:15:11you're going to increase.

00:15:13one guy square or two guys square at a given anime three guys square the three guys square

00:15:19the upper can never know you not by night or you value value hydrogen man minus 1.5 one

00:15:26it I tell you a personal 16 yeah period minus one point eight five five electron world yeah

00:15:36yeah it's a couple things first excited a girl electron first orbit man so yeah I say

00:15:46idea to you have a look at that 10.2 your job 10.2 your energy difference of eyes

00:15:52I will say first, excitation, energy.

00:16:04First, excitation, energy, which means where you go, just above the way you need to go.

00:16:11How do you need to go?

00:16:1210.

00:16:13So, this value is 10.2 electron volts.

00:16:17If you say second, then you can say second, then you can say,

00:17:38excitation potential a term use key at the excitation potential are a fast excitation

00:17:45energy kittany a 10.2 electron world get a potential then I put a guy 10.2 world that

00:17:52though 10.2 world electron code the dog at the energy kittany person guy 10.2 electron

00:17:58world work for say second bachelor I say second excitation potential can I 12.09

00:18:06world are potential word or potential excitation energy has eq a difference

00:18:12either मुझे एक और वेट से दूसी और वीड पर जाने के लिए 40 electron

00:18:19volt energy चाहिए हूए किसी बेटाल इस अडीर उडाल जा रहा है कि

00:18:23excitation energy जो है वो 40 electron volt है तो excitation potential

00:18:2840 volt रहा होगा तभी जाकर उसके पास extra energy 40 electron volt आई होगी और

00:18:34If excitation energy is 40 electron volts, then the excitation potential will be 40 volts.

00:19:04If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:19:34If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:19:41If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:19:48If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:19:55If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:20:02If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:20:09If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:20:16If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:20:23If excitation energy is 40 volts, then the excitation potential will be 40 volts.

00:20:26If excitation will be 30 volts, then the excitation potential will be 40 volts, then the excitation will be 40 volts.

00:20:39I said it's quite common

00:20:41I don't know me yeah

00:20:43I'm going to come here

00:29:18यह हमारे नए energy

00:29:21आए अगर reference हमने

00:29:23first orbit की potential energy

00:29:25zero लिया

00:29:25question change हमसे question में बोला जा रहा है

00:29:29कि यह

00:29:30ना हमें question में बोला जा रहा है

00:29:34if

00:29:34potential energy of second

00:29:37orbit

00:29:38is taken as zero

00:29:42second वाले को zero लेना है

00:29:45तो second वाले को

00:29:48zero लेना है तो मैं second वाले के लिए

00:29:49पहले कारेकरम स्टार्ट कर रहा हूँ

00:29:51second वाले के लिए kinetic

00:29:53potential और total

00:29:55अच्छा सेकेंड वाले के लिए total hydrogen चल रहा है

00:29:59hydrogen इसकेंड वाले में

00:30:01minus में

00:30:02minus में 3.4

00:30:05इसका positive क्या आता है

00:30:073.4 और इसका double कितना आता है

00:30:106.8 अब करना क्या है

00:30:12इसको zero करना है

00:30:14तो zero करना है तो इसमें क्या add करना पड़ेगा

00:30:176.8 एड करना पड़ेगा

00:30:20इस बार second वाले को reference लेने की कह रहा है

00:30:23तो इसको zero करेंगे

00:30:24तो यह वाली value अब क्या बन गई

00:30:26जो उसने बोला था वो zero

00:30:28अब जब इसमें add क्या है

00:30:30यार काइनेटिक में कुछ add नहीं होता है

00:30:32तो काइनेटिक क्या है तो velocity से लिटेड है

00:30:35वो reference वाले से इसका कोई लेना देना नहीं कि कहाँ पर है

00:30:38अच्छा

00:30:38काइनेटिक मेकनिक्स में पढ़ो काइनेटिक भी reference में डिपेंट करता है

00:30:43लेकिन वो reference क्या है relative velocity

00:30:46यहां पर potential में reference क्या है

00:30:49कहां से position से देख रहे है

00:30:53और काइनेटिक में जो reference आएगा वो कॉल देख रहा है

00:30:57दो नमें डिफरेंस जो देख रहा है उसकी speed है नहीं

00:31:00तो यहां तो यह आया अच्छा यहां पर भी क्याइड करना पड़ेगा

00:31:03six point यह कितना आ जाएगा three point four

00:31:07ना भई मज़ा नहीं आया फर्स और बीट पर कारेकरम चलाओ

00:31:10अगर पूछा जाए इसको zero second वाले को

00:31:13reference ले लूँ तो first के एनर्जिस बताओ

00:31:15तो first के लिए kinetic potential और total मुझे पहले की पता है

00:31:20total क्या होती है hydrogen में minus 3.6 plus में 3.6 यह

00:31:26minus में 27.2 लेकिन अब मुझे reference लेना था

00:31:30second orbit का उसके लिए मैंने कितना add किया वई तो इसमें

00:31:34भी add करना इसमें क्या third fourth fifth sum में add करना पड़ेगा

00:31:37ऐसे इसमें add नहीं करते हैं इसमें करना पड़ेगा add तो यह यह वाली वैल्यू तो

00:31:42काइनेटी का भी भी 13.6 एलेक्ट्रन वोल्ट है यह वाली वैल्यू हमारे पास में कितना आ जाएगा

00:31:47add करने पर minus 20.4 और यह वाली वैल्यू कितना जाएगा

00:31:54माइनस में 6.8 यह सब के अंसर आ गये किसी के लिविग्योशन में लिखे इसको समय मैं आ गया तो इसका थर्ड फॉर्थ किसी भी और बेट कर लेकर वाय सकते हैं

00:32:06नहीं

00:32:12झाल

00:32:42अरे कब आ गए

00:32:45अब आई गई है तो पही लेते हैं

00:32:55अब आई गई है तो पही लेते हैं

00:32:55अब आई हैं
