Assertion : The work done during a round trip is always zero. Reason : No force is required to move a body in its round trip.

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
In a round trip work done is zero only when the force is conservative in nature.
Force is always required to move a body in a conservative or non-conservative field
