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

Two equal positive charges Q are fixed on the x-axis, one at +a and the other at -a.

(a) The electric field E at the Origin O

(b) The electric potential V at the origin O

2. Relevant equations

E=-dV/dr --> V=kQ/r

3. The attempt at a solution

V_{Net}= V_{0}+ V_{1}

I got V_{0}= -kQ/r (because the vector r is negative)

..and V_{1}= kQ/r

V = 0

Is this correct?

Thank you for your help!
