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

Show that in this set-up, the potential at a generic point (-x, 0, 0) (for x positive) is zero:

two point charges placed at (-a, 0, +a) and (-a, 0, -a)

the mirror charges are (a, 0, +a) and (a, 0, -a)

3. The attempt at a solution

V=(q/(4 pi epsilon0)) ((1/(sqrt((x^2 -a^2)+a^2))+(1/(sqrt((x^2 -a^2)+a^2)))

this does not equal zero

by the way, please DO NOT DELETE THIS POST, MODS, I ASSURE YOU I HAVE NOT POSTED THE SAME QUESTION. IT IS A TOTALLY DIFFERENT PART OF A QUESTION I POSTED EARLIER.
