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 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!
