In which case does the potential energy decrease
Text Solution
Verified by ExpertsThe correct answer is:
D
In compression or extension of a spring work is done against restoring force.
In moving a body against gravity work is done against gravitational force of attraction.
It means in all three cases potential energy of the system increases.
But when the bubble rises in the direction of up thrust force then system works so the potential energy of the system decreases.
