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

Electric charge is distributed along each side of a square. Two adjacent sides have positive charge +Q on each, two sides have -Q on each.

What are the x and y components of the net electric field at the center of the square? (Each side has length "a").

2. Relevant equations

E=F/q ?

F=k*q1*q2/r^2

k=9E9Nm^2/C^2

3. The attempt at a solution

Trying to come up with a differential equation? I don't know how to begin with having 4 sides.
