Net Electric Field Homework Solution

Homework Statement

Homework Equations

E=kq/r²

The Attempt at a Solution

So i decided to do decouple the x and y values to make it simpler
For E_x It became apparent through the geometry and charges that there would be no net field in the x direction

For E_y:
k/r²* (-absq₁+absq₂+absq₃-absq₄)sinθ
= 8.99E9/(.5*√2*.067)*(-6.31E-9+18.6E-9+18.6E-9-631E-6)sin(π/4)
=3295.12 N/C

Nevermind, forgot to square the distance.
