Question

A force - time graph for a linear motion is shown in the figure where the segments are circular. The linear momentum gained between zero and `8 s` is

A. `- 2pi N - s`
B. Zero
C. `-4 pi N - s`
D. `-6 pi N -s`

Answer 1

Correct Answer - B
The area of `F -t` graph gives change in linear momentum.
`t = 0 to t = 8 s , area = 0 = Delta p`
