(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A positive charge +q1 is located to the left of a negative charge -q2. On a line passing through the two charges, there are two places where the total potential is zero. The first place is between the charges and is 4.00 cm to the left of the negative charge. The second place is 7.00 cm to the right of the negative charge. (a) What is the distance between the charges? (b) Find q1/q2, the ratio of the magnitudes of the charges.

2. Relevant equations

Not sure which one to use. the EPE one or kq1/x = kq2/d-x

3. The attempt at a solution

Ok...This might be one of the most confusing questions I've ever encountered in Physics! I drew a diagram, but i had no clue what i was doing. I know the equation V = Kq/r is supposed to be used, but i don't know what to substitute in the problem!!! please show me how you do this problem. appreciate all the help i can get! WHAT IS Q1 AND Q2??? my main problem

Book Answer: I only have part b, which is 3.67
