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

Three charges are laid out in a Cartesian Plane:

+q: (0,a)

-q: (0,0)

+q: (0,-a)

There is some point p located on the x-axis in the positive x direction

Show that the points where the Electric potential is 0 is x= +/- a/sqrt(3)

2. Relevant equations

I believe I am to use

[tex]

\begin{flalign*}

V = \frac{1}{4 \pi \epsilon_0} \ \frac{q}{r}\\

\end{flalign*}

[/tex]

because they are point charges

3. The attempt at a solution

I created right triangles using "P" as a point to start pythagorizing( is that a word?). Eventually I simplified it to q/(x(sqrt(a^2+x^2))

No idea how to get it to +/- a/sqrt(3)
