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