A nonzero external force on a system of ...

A nonzero external force on a system of particles. The velocity and the acceleration of the cente of mass are found to be `v_0 and a_0` at an instant t. It is possible that

A

`v_0 = 0, a_0 = 0`

B

`v_0 = 0, a_0 != 0`

C

`v_0 != 0, a_0 = 0`

D

`v_0 != 0, a_0 != 0`

Text Solution

Verified by Experts

The correct Answer is:
B, D
As external force is non-zero so at this instant acceleration is non zero, but velocity may or may not be zero
