1. The problem statement, all variables and given/known data A charge of -3.02 micro C is located at the origin abd a charge of -2.44 micro C is located along the y axis at 2.6109 m. At what point along the y axis is the electric field zero? 2. Relevant equations E = q/ r^2 3. The attempt at a solution first i determined equations to use for "r" (distance) r1 = y2 (2.6109m-y)^2 r2 = I set the electric fields equal to zero E2-E1 = o k(2.44 micro C)/(6.8168-6.8168y=y^2) - k(3.02 micro C)/y2 =0 Then i just solved these as a quadratic in the end but the answer under the square root comes out as a negative or as a ridiculously large number. Please guide me through. Much appreciated!
