Electrostatic Potential Energy
Electrostatic potential energy of a system of point charges is defined as the total amount of work done in bringing the different charges to their respective positions from infinitely large mutual separations.
By definition, work done in carrying charge from `oo` to any point is
W = Potential `xx` Charge
This work is stored in the system of two point charges in the form of electrostatic potential energy U of the system.
Two similar positive point charges each of `1 muC` have been kept in air at 1m distance from each other. What will be the potential energy?
Options:
(a) `1 J`
(b) `1eV`
(c) `9 xx 10^(-3)J`
(d) zero
