## Homework Statement

## Homework Equations

E=k

_{e}*q/r

^{2}

## The Attempt at a Solution

See screenshot. The angles are correct, however I can't get the equation right for either part. I understand they should be different since one is force and the other electric field, I thought that should be the electric field solved and simplified.

Not sure how to put in equations on here, so I'll do my best.

before simplification, I had for the i component:

k

_{e}3q/a

^{2}+sqrt(2)/2*k

_{e}4q/a

^{2}

and for the j component:

k

_{e}5q/a

^{2}+sqrt(2)/2*k

_{e}4q/a

^{2}

where have I gone wrong? the sqrt(2)/2 is cos(45) and sin(45) to get the components of the Bq in the drawing. Not sure what the problem is. I can do these fine with numbers so maybe I just am not putting it into the computer right. suggestions?
