1. The problem statement, all variables and given/known data 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. 2. Relevant equations EF (field) = (k q) / r^2 where EF = 0 k = 9e9 3. The attempt at a solution I know im looking for r, but the way i setup the equation gives me 2 unknowns.
