Class 11 Physics MCQs (Questions & Answers)

Q1. What is the increase in potential energy storage when the compression distance is doubled in a spring obeying Hooke’s law?
A) No increase
B) 100% increase
C) Cannot be determined
D) 4 times

Answer: D
Explanation: The elastic potential energy stored is directly proportional to the square of the compression. Hence, a two-fold increase in compression will result in potential energy storage to increase by four times.
