A point charge of -4 mu or micro CC is located at x = 4 m, y = -2 m. A second point charge of 12 mu or micro CC is located at x = 1 m, y = 4 m.

(a) Find the magnitude and direction of the electric field at x = -1 m, y = 0.

I got 4545.69 N/C by using this equation E= kQ/r^2 (vector r) and finding EQ1 and EQ2 then finding their x and y components and adding those then taking the magnitude. but my answer is wrong.
