The potential energy of a system increases, if work is done

A

upon the system by a non-conservative force

B

upon the system by a conservative force

C

by the system against a non-conservative force

D

by the system against a conservative force

Text Solution

Verified by Experts

The correct Answer is:
D
Work done by the conservative force `=-DeltaU`
`therefore` For `DeltaUgt0` work done `lt0`
`therefore` U increases if work is done against conservative force.
