NEET Physics Work Done by Forces MCQ Question
Consider a diagram of a block attached to a spring, where the x-axis represents displacement from the equilibrium position and the y-axis represents the spring force. Which statement correctly describes the work done by the spring force when the spring is compressed?
The work done is negative, as the spring force opposes the displacement.
The work done is positive, as the spring force assists the displacement.
The work done is zero, as the spring does not move.
The work done is constant, irrespective of the displacement.
Correct Answer
Detailed Explanation
The work done by the spring force is negative when the spring is compressed because the spring force opposes the displacement, as described in the NCERT context about the spring force and displacement.
