Q. When a positive $q$ charge is taken from lower potential to a higher potential point, then its potential energy will
A) Decrease
B) Increase
C) Remain unchanged
D) Become zero
Explanation
(b) $\mathrm{\Delta}\ P.E.\ =$ Work done by external agent
$= \left( V_{f}q - V_{i}q \right),\ V_{f} > V_{i} \Rightarrow \mathrm{\Delta}P.E. > 0\ i.e.P.E.$ will increase
