00:08Assalamualaikum dear students,
00:11Today we will do conversion.
00:15The conversion is in SI the value of gravitational constant.
00:21SI system means gravitational constant means capital G ka value
00:266.67 into 10 raise power minus 11 newton into meter square per kilogram square.
00:33Is ko hum convert karenge in CGS system.
00:47CGS mein is ka value kya hooga wo hum conversion karenge.
00:52As we know that in SI the value of G is 6.67 into 10 raise power minus 11 newton
01:04into meter
01:04square per kilogram square.
01:07As we know that 1 newton is equal to 10 raise power 5 dyne and 1 meter square will be
01:21equal
01:24to 10 raise power 2 centimeters whole square.
01:31So, it will be 1 meter square will be equal to the square of 10 raise power 2 is 10
01:37raise
01:37power 4 and the square of centimeter is centimeter square.
01:46And kilogram.
01:48We will convert kilogram into grams.
01:53As we know that 1 kilogram is equal to 10 cube grams.
01:59So, 1 kilogram square will be equal to 10 cube grams whole square.
02:11So, 1 kilogram square will be equal to the square of 10 cube.
02:22The square of 10 cube is 10 raise power 6 and the square of gram is gram square.
02:30So, now we will put these values here.
02:36So, G will be obtained as 6.67 into 10 raise power minus 11.
02:46The square of gram is equal to 10 raise power 5 dyne multiplied with meter square.
02:56The value of meter square is 10 raise power 4 centimeter square.
03:18The square of gram square is equal to 10 raise power 6.
03:27So, the value of the gram square is equal to the square of gram square.
03:33minus 11.
03:36Yahaan per multiplication mein basis same mein to powers ko kya karengi 8 karengi so it will
03:42be tangles powers 5 plus 4 it will be tangles power 9 9 into centimeter square per yah
03:52upon tangles power 6 gram square.
03:56So, g will be equal to 6.67 into 10-12 or minus 11.
04:03Achaan per basis same mein to powers 8 karengi e multiplication mein so ye minus 11 or ye
04:11plus 9 9 centimeter square upon 10-12 power 6 gram square same lekinge so g will be equal
04:23to 6.67 into 10-12 power minus k 11 plus k 9.
04:59So, it will be minus 2.
05:00So, unit will be dine centimeter square per gram square.
05:07So, yahaan per bhi multiplication mein basis same mein to powers 8 karengi so g will be equal
05:13to 6.67 into 10-12 power minus 2 minus 6 dine into centimeter square upon ground square.
05:24So, yahaan per plus plus jab hum karengi to joh nishaniyah hoti hain wo hi hum rakhethe
05:30he.
05:31Yeh minus kai hai to yeh minus kai rahe ga, yeh bhi minus kai rahe ga.
05:34So, finally, we will get the value of g in CGS as 6.67 into 10-12 power minus 2
05:46minus 6.
05:47It will be minus 8 dine into centimeter square per gram square.
05:55So, this is our required value means in SI the value of capital G means gravitational
06:07constant is 6.67 into 10-12 power minus 11 Newton into meter square per kilogram square.
06:13And in CGS system its value will be 6.67 into 10-12 power minus 8 dine into centimeter square
06:21upon gram square.
