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.
Work done in moving a charge from one point to other inside a uniformly charged conducting sphere is
Options:
(a) always zero
(b) non-zero
(c) may be zero
(d) None of these
