NEET Physics (general) MCQ Question

Type: MCQ-numerical-Hard-Class 11

A block of mass 2 kg is attached to a massless spring with a spring constant of 500 N/m. The block is compressed by 0.1 m from its equilibrium position on a frictionless surface. What is the potential energy stored in the spring at maximum compression?

A

5 J

B

5 J

C

10 J

D

20 J

Correct Answer

Option B

Detailed Explanation

The potential energy stored in a spring is given by the formula 12kx2\frac{1}{2} k x^2, where kk is the spring constant and xx is the compression. Substituting the given values, 12×500×(0.1)2=5\frac{1}{2} \times 500 \times (0.1)^2 = 5 J.
