Homework Statement
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
Homework Equations
E=-dV/dr --> V=kQ/r
The Attempt at a Solution
VNet = V0 + V1
I got V0 = -kQ/r (because the vector r is negative)
..and V1 = kQ/r
V = 0
Is this correct?
Thank you for your help!
