Identify the $WRONG$ statement

A

The electrical potential energy of a system of two protons shall increase if the separation between the two is decreased.

B

The electrical potential energy of a proton electron system will increase if the separation between the two is decreased

C

The electrical potential energy of a proton electron system will increase if the separation between the two is increased

D

The electrical potential energy of system of two electrons shall increase if the separation between the two is decreased

Solution

For similar charge, $PE$ increases with decreases in $r.$ For dissimilar charge $PE$ decreases with decrease in $r.$

As $P.E.\, = \,\frac{{{Q_1}{Q_2}}}{{4\pi {\varepsilon _0}r}}$
