1. The problem statement, all variables and given/known data A 3.03μC and a -1.93μC charge are placed 4.14 cm apart. At what point along the line joining them is the electric field zero? Assume that the first charge is at the origin and the second charge is at +4.14 cm. what points along the line joining them is the potential zero? Let V = 0 at r = infinity. 2. Relevant equations E=kq/r^2 and V=kq/r 3. The attempt at a solution I already solved for the part about the electric field, the answer was r=2.05cm. For the second part of the question I tried... Vtotal=V1+V2 0=kq1/r1+kq2/r2 -q2/r2= q1/r1 but I am not sure what the two distances are supposed to be. Also how would this give me two different answers?
