A positive charge of q1 is located 4.59 m to the left of a negative charge q2. The charges have different magnitudes. On the line through the charges, the net electric field is zero at a spot 1.20 m to the right of the negative charge. On this line there are also two spots where the potential is zero.
(a) How far to the left of the negative charge is one spot?
(b) How far to the right of the negative charge is the other?
