A heavy weight is suspended from a spring . A person raises the weight till the spring becomes slack . The done by him is `W`. The energy stored in the stretched spring was `E` . What will be the gain in gravitational potential energy?

(a) W

(b) E

(d) `W-E`

Text Solution

Verified by Experts

The correct Answer is:

Total gravitational energy gained is work done +energy released by the spring `=W+E`
