Question

Assertion : The work done by the spring force in a cyclic process is zero.
Reason : Spring force is a conservative force.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

In case of spring force, the work done only depends on the initial and final positions. So spring force is a conservative force and in cyclic process the initial and final positions are same, hence work done is zero.
