1. The problem statement, all variables and given/known data Two equal point charges of magnitude 4.0 μC are situated along the x-axis at x1=-2.0m and x2= 2.0m. What is the electric potential at the origin of the xy coordinate system? 2. Relevant equations ΔV= Kc (q/r) 3. The attempt at a solution Do voltages cancel each other out at the mid point or do they add up?
