Physics-Work Done by Forces
NEET Physics Work Done by Forces MCQ Question
Type: MCQ-numerical-Medium-Class 11
A spring is compressed by a displacement of 0.2 m from its equilibrium position. If the spring constant k is 500 N/m, what is the work done by the spring force during this compression?
A
-10 J
B
-5 J
C
10 J
D
5 J
Correct Answer
Option A
Detailed Explanation
The work done by the spring force is given by W = -1/2 k x^2. Substituting k = 500 N/m and x = 0.2 m, W = -0.5 * 500 * (0.2)^2 = -10 J.
