Homework Help: Electric Potential

  1. Sep 17, 2008 #1
    1. The problem statement, all variables and given/known data
    Two point charges q and -q are located on the z axis at (x,y,z) = (0,0,a) and (0,0,-a) respectively.

    Find the potential [tex]\phi[/tex] everywhere

    3. The attempt at a solution

    I know all the equations and such, I just don't know how to integrate it. I am guessing that it is in cylindrical coordinates.

    I don't think cylindrical coordinates or integration will be necessary. What is the formula for the potential due to a point charge? And are you familiar with the principle of superposition?
