Assertion , No work is done if the displacement is zero
Reason: Work done by the force is defined to be the product of component of the force in the the direction of the displacement and the magnitude of displacement.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true not but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
