Question

define electric potential energy.Give its units.calculate electric potential energy of a system of point charge.​

Answer 1

Answer:

Electric potential energy, or Electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. An object may have electric potential energy by virtue of two key elements: its own electric charge and its relative position to other electrically charged objects.

SI unit : Joule (J)

The equation for the electric potential due to a point charge is

$V=\frac{kQ}{r}$, where k is a constant equal to 9.0×109 N⋅m2/C2.
