Electrostatic Potential Energy question from NEET 1999 (AIPMT)

Q64NEET 1999 · AIPMTEasy

Electrostatic Potential Energy

In bringing an electron towards another electron, the electrostatic potential energy of the system

Show answer and solution

Answer: (b)

$U = \dfrac{k(-e)(-e)}{r} = \dfrac{ke^2}{r} > 0$
As $r$ decreases, $U$ increases (work is done against repulsion).
So the answer is (b) increases.
