## Homework Statement

Two small charges 6e-5 and -2e-5 C. are placed 0.36m apart. Calculate the following:

e) the point at which the magnitude of the electric field is zero.

## Homework Equations

EF (field) = (k q) / r^2

where EF = 0

k = 9e9

## The Attempt at a Solution

I know im looking for r, but the way i setup the equation gives me 2 unknowns.
