If net force on a right body zero, it is...

If net force on a right body zero, it is either at rest or moving with a contact linear velocity. Nothing else can happen.
Contant velocity means linear acceleration is zero

A

If both Accertion and Reason are true and the reason is correct explanation of the Assertion.

B

If both Accertion and Reason are true but reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
If net force zero but net torque `!= 0` then it can rotate.
