NEET 2023 Physics Elastic Potential Energy MCQ Question with Solution

The potential energy of a long spring when stretched by 2 cm is U. If the spring is stretched by 8 cm, potential energy stored in it will be:

A

4U

B

8U

C

16U

D

2U

Correct Answer

Option C

Detailed Explanation

Potential energy in a spring is proportional to the square of the extension. If the extension increases from 2 cm to 8 cm, the energy increases by a factor of $\left( \frac{8}{2} \right)^2 = 16$ .
