Question

When a conservative force does positive work on a
(1) Potential energy of body increases
(2) Potential energy of body decreases
(3) Total mechanical energy of body increases
(4) Total mechanical energy of body decreases
plz explain​

Answer 1

Answer:

4

Explanation:

Total mechanical energy of body decreases

Answer 2

Answer:

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.
