Question

Assertion : A spring has potential energy, when it is either compressed or stretched.
Reason : In compressing or stretching a spring, work is done on it against the restoring 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)

Work done on the spring is stored in the spring in the form of potential energy as restoring force is always opposite to applied force.
