# Solution - When a Conservative Force Does Positive Work on a Body, the Potential Energy of the Body Increases/Decreases/Remains Unaltered. - CBSE (Science) Class 11 - Physics

ConceptThe Concept of Potential Energy

#### Question

Underline the correct alternative:

When a conservative force does positive work on a body, the potential energy of the body increases/decreases/remains unaltered.

#### Solution 1

Decreases

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.

#### Solution 2

Potential energy of the body decreases, because the body in this case goes closer to the centre of the force.

Is there an error in this question or solution?
