## Homework Statement

Two particles are situated on the x axis. The particle q1, with 34 excess electrons, is situated at the point x = 100 μm. The other particle q2, with 17 excess electrons, is located at the origin. Give the x value of a point between the particles where the strength of the field they generate is zero.

## Homework Equations

So kQ/r^2 is important here. The addition of electric field strength must give 0 N/C.

## The Attempt at a Solution

I'm not even sure where that x value would fall into. Would it be between the two charges or to the right of -34e or to the left of -17e. kq1/x^2 +kq2/(x-100e-6)^2=0 is the equation I tried to solve for x, but the function is asymptotic to the x axis, so, the answer is infinity. But that wasn't the answer in the back of the book, so figure it out.
