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

The figure shows a system consisting of three charges, q1=+5.0uC, q2=+5.0uC and

q3=-5.0uC, at the vertices of an equilateral triangle (with q2 at the top point of the triangle).

Find the magnitude of the electric field at a point halfway between the charges q1 and q2.

distance= 2.95cm

2. Relevant equations

i know an equation is E= k q/r^2

3. The attempt at a solution

So since it wanted to know the halfway point, I divided the distance between the points in half and used it as r. And I figured that the charges have an x and y component but what angles do I use??
