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] everwhere



    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.

    Why do you need to integrate it? Just find the potential at any point due to q and the one due to -q and add up the two. This one you can easily apply the formula for potential due to point charge.
