00:00question says the graph between force and time for which force acts on the

00:15body is shown in the figure below the change in the momentum of the body is a

00:2215 Newton second B 150 Newton second C 300 Newton second D 0 is area under the

00:34force time graph is equal to change in momentum so change in momentum is equal

00:45to 1 upon 2 into base into height is change in momentum is equal to area of

01:03the triangle so change in momentum will be equal to 1 upon 2 into the base point

01:14is obtained as 0.3 so 0.3 into height is force is taken along y-axis so in place

01:29of height we will take the value of force which is obtained as 100 Newton so

01:36it is into 100 so change in momentum will be obtained as 1 upon 2 into a 0.3

01:46into 100 it will be 30 so the table of 2 on 2 is 1 times and on 30 is 15 times so

01:56change in momentum will be obtained as 15 Newton second so the correct option

02:06will be a 15 Newton into second
