1. The problem statement, all variables and given/known data A 1.8e-6 C charge is at the origin, while a -7.71e-6 C charge is 10cm to the right of it. Locate the x coordinate such that E=0. Note: q1 is at the origin O. Answer in units cm. 2. Relevant equations Etot=E1+E2 Etot=(-k*q1/x^2)+(k*q2/(0.1+x)^2) (k*q1/x^2)=(k*q2/(0.1+x)^2) 3. The attempt at a solution I promise you I have attempted this equation. I'm not going to type it all out here. I have a sheet full of scratch work. The answer I keep getting is 1.96.
