1. The problem statement, all variables and given/known data Three pointcharges are located at the following points on an x-y coordinate system, Q1 = -3 uC at (0,0) q2 = 10.0 uc at (0,0.5m), and q3 = -3 uC at (x,0) . What is the total electric potential at the point (x/2,0) where x is in units of m. At what value does x have to be, for the potential at point (x/2,0) =0 2. Relevant equations Vp =V1+v2+v3 V= k * q/r 3. The attempt at a solution V= k([-3/(x/2)) + (10/(sq rt (.5 =(x/2)))+(-3/(x/2)) Am I going about this wrong? Should i do a vector analysis of the electric field? How do i get this to all = 0?
