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

A

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

B

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

C

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

D

Zero

Text Solution

Verified by Experts

The correct Answer is:

D

From 0 to T, area is +ve and from T to 2T, area is -ve. Net area is zero. Hence, no change in momentum.
