## Homework Statement

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?

## Homework Equations

E = q/ r^2

## 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!
