The balancing point between two point charges

[UnD3R0aTh]

Where is the potential zero?

1. Where is the potential zero between a negative (-.03c) and a positive charge (.27) separated by 1 meter?
2. Point charges laws
3. My textbook doesn't mention where is potential zero between two charges, it's easy to solve if i know the point is in between or outside and which point charge is it closer to, kq/d=kq/d

hints;

[tex]\frac{k\cdot 0,27}{d}+\frac{k\cdot (-0,03)}{D}=0[/tex]

two different d.

And you need another equation...
