1. The problem statement, all variables and given/known data A positive charge of +q1 is located 3.00m to the left of a negative charge -q2. the charges have different magnitudes. a) on the line through the center of the charges, the net electric field is zero at a spot 1.00m to the right of the negative charge. Determine the relative magnitude of the charges (charge ratio q1/q2) b) on this line there are two spots where the potential is zero. locate these two spots relative to the negative charge. 2. Relevant equations Ue=kq1q2/r V=Ue/q V=kq/r 3. The attempt at a solution for part a i got q1=+16 and q2=-1 I'm not sure how to find these zero potential spots. I know they're supposed to be near the smaller negative value but I just can't figure out how to calculate out exactly where.
