Electric filed:

$\overline{){\mathit{E}}{\mathbf{=}}\frac{\mathbf{kq}}{{\mathbf{r}}^{\mathbf{2}}}}$

Let the distance from q_{1}, theN r_{1} = x.

r_{2} = (s - x)

At the zero filed point:

Finding the Zero-Field Point

Two particles with positive charges *q*_{1} and *q*_{2} are separated by a distance *s*.

Along the line connecting the two charges, at what distance from the charge *q*_{1} is the total electric field from the two charges zero?

Express your answer in terms of some or all of the variables *s*, *q*_{1}, *q*_{2} and *k*=1/4*π**ϵ*_{0}. If your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
