NEET Physics Work Done by Forces Assertion Reason Question
Assertion (A): The work done by the spring force is negative when the spring is stretched or compressed.
Reason (R): The spring force is always opposite in direction to the displacement of the spring.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The work done by the spring force is negative because the spring force opposes the displacement. This aligns with the explanation given in the NCERT context that for a stretched spring, the spring force Fs is negative when displacement x is positive and vice versa.
