This is the question I have: consider the system formed by two infinitely long line charges located in the xy plane running parallel to the x axis at y = + and - a and carrying uniform charge densities + and - lambda respectively. Find the elctrical potential at all points in space using the origin as your referenc point.(adsbygoogle = window.adsbygoogle || []).push({});

Because the lines of charge do not run along the x axis, I assume that I'm going to have to use curly r in my answer (ie. r minus r prime). So, assuming I use the equation that involves the integral of lambda over curly r, integrated over r prime, how do I rewrite curly r so that I can integrate properly?

Or am I going about this all wrong?

Any advice would be appreciated.

W. =)
