Find magnitude and direction of the electric field this combination of charges produces at point P, which lies 6.00 from the - charge measured perpendicular to the line connecting the 3 charges. Assume = 5.50 and = 2.50

I was able to get the x components and I know the net force for the y components is zero. I also know the direction would be toward -q2.

For q1 I got F=[kq1/(0.08^2)]*(0.06m/0.08m)^2 and for q2 F=kq2/(0.06^2)

Do I plug in all the numbers and then use the forces to find the electric fields of each charge and then add them together?
