Energy stored in a system of three point charges

Description

Electric potential energy, or electrostatic potential energy, is a potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. The electrostatic potential energy stored in the system of three charges can be calculated by the three charges and the distances between the points. (The electrostatic potential energy of a system of three charges should not be confused with the electrostatic potential energy of Q1 due to two charges Q2 and Q3, because the latter doesn’t include the electrostatic potential energy of the system of the two charges Q2 and Q3.)
