A spring with k = 100 N/m is compressed by 0.2 m. What is the potential energy stored?
Q1. A spring with k = 100 N/m is compressed by 0.2 m. What is the potential energy stored?
Answer: 2 J
Explanation: Elastic potential energy = 0.5 * k * x^2 = 0.5 * 100 N/m * (0.2 m)^2 = 2 J. Option B is incorrect due to calculation error.
