Find the electrostatic potential above loop of charge Q?

[QUOTE="Klause, post: 5476142, member: 592160"] So potential due to a continuous distribution of charge : V= 1/(4πε[SUB]0[/SUB])∫dq/r Where r is the distance of the wire to the point at which you are trying to find the potential. In this case, D. So since the wire has a radius R. The r=√(R[SUP]2[/SUP]+D[SUP][/SUP]). This is because all points along the ring are at the same distance from the point at (0,0,D). So then plugging this into the first equation, do you notice anything interesting? Perhaps a constant you can factor out leaving you with an easy integral. [/QUOTE]
