## Homework Statement

## Homework Equations

Ex=1/k*1/(a^2/2)*1/(sqrt2)*cos(theta)*(sum of charges)

Ey=1/k*1/(a^2/2)*1/(sqrt2)*sin(theta)*(sum of charges)

## The Attempt at a Solution

So first off I can see that I don't need to calculate the force in the x direction as each q cancels out when arranged appropriately

For Ey I get:

Ey=1/k*1/(.067^2*2)*1/sqrt2*sin(45degrees)*(-6.31nC+18.6nC+18.6nC-6.31nC)*10^-9

=1.523E-16 N/C

Use Pythagorean theorem but that is unnecessary do to an absence of an x component
