NEET Physics Work Done by Forces MCQ Question
Consider a diagram showing a block of mass 2 kg resting on a smooth horizontal surface and attached to a spring fixed to a wall. The spring is compressed by 0.1 m. Which of the following statements correctly describes the work done by the spring force when the block is released and moves to the equilibrium position?
The work done by the spring force is positive.
The work done by the spring force is negative.
The work done by the spring force is zero.
The work done by the spring force is equal to the potential energy stored in the spring.
Correct Answer
Detailed Explanation
The work done by a spring force when it moves an object from a compressed position to the equilibrium position is positive, as the force and displacement are in the same direction.
