Text Solution

Verified by Experts
The correct answer is:
A

When a body does some work against friction, its kinetic energy decreases.

Work done by a body is independent of time.
Power of a body ( ) varies inversely as time.
When work done over a closed path is zero, force must be conservative.
Hence, A-II, B-I, C-III, D-IV
