Electrical Potential Energy
Category : JEE Main & Advanced
It is the energy associated with state of separation between charged particles that interact via electric force. For two point charge \[{{q}_{1}}\] and \[{{q}_{2}}\], separated by distance r.
\[U=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{{{q}_{1}}{{q}_{2}}}{r}\]
While for a point charge q at a point in an electric field where the potential is V
U = qV
As charge can be positive or negative, electric potential energy can be positive or negative.
