Two point charges lie along the y axis. A charge of q1 = -12.0 µC is at y = 7.0 m, and a charge of q2 = -2.0 µC is at y = -4.0 m. Locate the point (other than infinity) at which the total electric field is zero.
E = (K lql) / r^2
The Attempt at a Solution
I setup the two equation make E = 0
(K lq1l) / (7-y)^2 = (K lq2l) / (-4+y)^2
It's wrong, please correct my equation
