A particle is on a smooth horizontal plane. A force F is applied whose F-t graph is given. Then,

A

at `t_(1)`, acceleration is constant

B

initially body must be in rest

C

at `t_(2)`, acceleration is constant

D

both c and d are correct

Text Solution

Verified by Experts

The correct Answer is:
D
At `t_(2)`, force is constant
So, acceleration is constant.
At t = 0, force is zero. Hence, acceleration is zero.
