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.

(a) What is the electric potential energy of two electrons separated by 3.00 nm? (b) If the separation increases, does the potential energy increase or decrease ?

Assertion : When two positive point charges move away from each other, then their electrostatic potential energy decreases. Reason : Change in potential energy between two points is equal to the work done by electrostatic forces.

As an electron makes a transition from an excited state to the ground state of a hydrogen like atom/ion (a) kinetic energy, potential energy and total energy decrease (b) kinetic energy decreases, potential energy increases but total energy remains same (c ) kinetic energy and total energy decrease but potential energy increases (d) its kinetic energy increases but potential energy and total energy decrease

Assertion: When two unlike charges are brought nearer, their electrostatic potentiasl energy decreases. Reason: All conservative forces act in the direction of decreasing potential energy.

Asseration : If work by done conservative forces is positive, kinetic energy will increase. Reason : Because potential energy will decrease.
