NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram showing a spring attached to a block. The spring constant is k, and the displacement from the equilibrium position is x. Which of the following correctly represents the work done by the spring force when the spring is compressed?
A
W = -1/2 k x^2
B
W = 1/2 k x^2
C
W = k x
D
W = -k x
Correct Answer
Option A
Detailed Explanation
The work done by the spring force is given by W = -1/2 k x^2 when the spring is compressed, as derived from the expression involving the area under the force versus displacement curve.
