## Homework Statement

An electric charge q1 (-6e) is located at the origin. A second electric charge q2 (+2e) is located a distance "d" from the origin. In terms of "d", what is the distance "x" from q1 where the net electric potential is zero? Assume for this problem that x<d.

**2.Relevant equations**

I need a solid explanation on how to do this problem properly. I have a strong feeling that this can't be right (my attempt). I need to be able to understand and work problems like this for my upcoming exam. Any help would be appreciated.

## The Attempt at a Solution

Vtotal = V1 + V2.

If Vtotal = 0 then V1+V2=0.

V1-V2

kq1/x = - kq2/d-x

q1/x = - q2/d-x

(q1(d-x))/(-q2) = x

3(d-x) = x

3d = 4x

(3d/4) = x[/B]
