Homework Statement
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)
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
