1. The problem statement, all variables and given/known data Point charges of -7 µC, 1.0 µC, and +7 µC are located along the x axis at x = -1.0 cm, x = 0, and x = +1.0 cm, respectively. Locate a point on the positive x axis where the magnitude of the electric field is zero. 2. Relevant equations E=(kQ)/r^2 E(total)=E(1)+E(2)+E(3) 3. The attempt at a solution I feel like I have the correct setup of the equation and just wanted to confirm: E=0=-(7e-6/(x+1)^2)+(1e-6/(x^2))-(7e-6/(1-x)^2) From this point I'm not really sure on how to proceed with solving for x.
