(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The electric field on the dashed line in the figure vanishes at infinity, but also at two different points a finite distance from the charges.

Identify the regions in which you can find E = 0 at a finite distance from the charges.

Check all that apply:

A)to the right of point C

B)between points A and B

C)to the left of point A

D) between points B and C

2. Relevant equations

E=kq/r^2

3. The attempt at a solution

I'm afraid that all I know is the formula, but I'm not sure how I'm supposed to apply it. Am I supposed to set E=0 or.. what? I feel like all I need is some direction in how to start and then I'll be able to get it.

Thanks!
