(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two point charges (opposite signs, equal in magnitude) are a distance d apart. Point P is a distance z above both charges and horizontally equidistant. Find the electric potential at point P.

2. Relevant equations

Kq/r

3. The attempt at a solution

It's my understanding that direction does not matter with potential so r is the same value for both. We can add the potentials together to get total potential. Plugging in q for the first charge and -q for the second gives 0.

I know that's not right, that would imply the electric field is zero which is obviously incorrect.

What am I doing wrong?
