hey guys i can't figure out this problem to save my life i thought i was doing it right using the
K=q/r^2 formula but its not coming out right. so if anyone can help me with this problem i would very much appreciate it.

In a rectangular coordinate system, a positive point charge = 3.50 is placed at the point x=0.190 ,y=0 , and an identical point charge is placed at x= -0.190 ,y=0 . Find the and components and the magnitude and direction of the electric field at the following points.

A) Find the and components and the magnitude and direction of the electric field at x=0.380, y=0.


B) Find E

Find the what and the components?

E=kq/r^2, not k=q/r^2. k is a constant.
