A unidirectional force F varying with time t as shown in the Fig. acts on a body initially at rest for a short duration 2T. Then the velocity acquired by the body is

A

`(piF_(0)T)/(4m)`

B

`(piF_(0)T)/(2m)`

C

`(F_(0)T)/(4m)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
From O to T, area is `(+)` ve and from T to 2T, area is `(-)`ve, net area is zero, hence, no change in momentum.
