Options

A. A-p,B-q,C-r,D-s
B. A-q,B-r,C-s,D-p
C. A-s,B-r,C-q,D-p
D. A-s,B-p,C-q,D-r

Answer

D

Explanation

When a body does some work against friction, its kinetic energy decreases. `therefore` A-s
Work done by a body is independent of time `therefore` B-p
Power of a body (P=W/t) varies inversely as time.
C-q
When work done over a closed path is zero, force must be conservative, `therefore` D-r
