[] Derive theof Electrostaticexpressionpotentialenergy

Answer»

Because it'sderivedfrom a force, it's a vector field. Theelectric potentialis theelectric potential energyof a test charge divided by its charge for every location in space. Because it'sderivedfrom anenergy, it's a scalar field.

Definition. ... Theelectrostatic potential energy, UE, of one point charge q at position r in the presence of anelectric fieldE is defined as the negative of the work W done by theelectrostaticforce to bring it from the reference position rrefto that position r.
