Question

Work done by a conservative force is positive if
(a) P.E. of the body increases
(b) P.E. of the body decreases
(c) K.E. of the body increases
(d) K.E. of the body decreases

Answer 1

Answer:

If work done by conservative forces is positive, kinetic energy will increase..

Hope this helps u ✌

Answer 2

Explanation:

A conservative force does a positive work on a body when it displaces the body in the direction of force. As a result, the body advances toward the centre of force. It decreases the separation between the two, thereby decreasing the potential energy of the body.Also kinetic energy increases.
