A force - time graph for a linear motion...

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`

Text Solution

Verified by Experts

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