Homework Statement
Locate the x coordinate such that E=0?
Coulomb constant is 8.98755x10^9 N m^2/C^2. The 1.68x10^-6 charge is at the origin and a -8.54x10^-6 charge is 10 cm to the right, as shown in the figure.

Locate the x coordinate such that E = 0. Note: q1 is at the origin O. Answer in units of cm.
Homework Equations
E=Fe/q
E=Kc(q/d^2)
F=Kc(q1q2/d^2)
F=1/(4pi(emf))*(q1q2/d^2)
The Attempt at a Solution
I've established that q1/(d)^2 should equal q2/(d+10)^2, but it seems I'm missing a component somewhere. I repeatedly get extremely small values, none of which satisfy the answer. I know that the placement of the charge will be left of the positive charge. Thanks in advanced if anyone knows what to do.
