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

A point charge q = +2.6 µC is placed at each corner of an equilateral triangle with sides 0.13 m in length.

What is the magnitude of the electric field at the midpoint of any of the three sides of the triangle?

2. Relevant equations

E=(kq)/r^2

Fx=(F1+F2)cos

Fy=(F1+F2)sin

F=Fx+Fy

3. The attempt at a solution

I first tried using the first equation, but I was pretty sure that I had to also use the other three equations, but I did not know how to properly solve for each of the F values. Am I supposed to use F=(kq1 q2)/r^2 ?
