In which case does the potential energy ...

In which case does the potential energy decrease ?

A

on compressing the spring

B

on stretching a spring

C

on moving a body against gravitational pull

D

on rising of an air bubble in water

Text Solution

Verified by Experts

The correct Answer is:
D
P.E. decreases when an air bubble rises in water, because work is done by upthrust.
