## Main Question or Discussion Point

I am wondering if there is some way for the force between two charges (calculated by Coloumb's law) and the force applied by a field on a charge.

Thanks in advance

What I am trying to do is find out how the electric potential of a radial field equation is derived. I have found a derivation by using Coulomb's Law and the equations for electric force, work etc however I do not understand the equation completely. This is because I do not know if the force between two charges (Coulomb's Law) and the force exerted on a charge by a field can be compared.

Thanks.

Take Coulombs's law, separate a q, call the rest an electric field E defined by [tex]E = \frac{kQ}{r^2}[/tex].

That's pretty much all there is to it. Once E is defined in this way, it paves the way for all of electrostatics. The same E then contributes to describe Maxwell's electromagnetic theory in its entirety.
