Question

Derive an expression for electrostatic potential energy of system of point charges

Answer 1

Potential Energy: Electric Potential Formula. ... Like all work and energy, the unit of potential energy is the Joule (J), where 1 J = 1 kg∙m2/s2 . The unit of charge is the Coulomb (C), and the unit of electric potential is the Volt (V), which is equal to a Joule per Coulomb (J/C).
