Question
A positive charge q1 is located 8.50 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 1.00 m to the right of the negative charge. On this line there are also two spots where the total electric potential is zero. Locate these two spots relative to the negative charge.
