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.

Assertion : When two masses come closer, their gravitaional potential energy decreases. Reason : In moving attract each other.

Assertion : When two masses come closer, their gravitational potential energy decreases. Reason : In moving attract each other.

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.

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.
