NEET Physics Work Done by Forces MCQ Question

Type: MCQ-diagram based-Hard-Class 11

Consider a block attached to a spring on a smooth horizontal surface, as described in the NCERT text. The spring force is plotted against the displacement from equilibrium. What does the area under the curve represent in the context of work done by forces?

Question diagram
A

The work done by the spring force, which is negative.

B

The work done by the spring force, which is positive.

C

The potential energy stored in the spring, which is positive.

D

The kinetic energy of the block, which is zero.

Correct Answer

Option A

Detailed Explanation

According to the NCERT context, the area under the force versus displacement curve represents the work done by the spring force, which is negative due to opposing signs of force and displacement.
