NEET Physics Work Done by Forces MCQ Question
Consider a block attached to a spring on a horizontal surface. The block is displaced from its equilibrium position, stretching the spring. Which statement correctly describes the work done by the spring force during this displacement?
The work done by the spring force is negative.
The work done by the spring force is positive.
The work done by the spring force is zero.
The work done by the spring force doubles if the displacement is halved.
Correct Answer
Detailed Explanation
Work done by the spring force is negative when the spring is stretched or compressed as the force opposes the displacement. This is consistent with the NCERT context where the work done is negative due to opposing signs of force and displacement.
