## Homework Statement

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.

## Homework Equations

E=(kQ)/r^2

E(total)=E(1)+E(2)+E(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.
