Question

We have a charge q = -0.6 x 10^-6 C at origin. And a vector r = (4 m, 3 m, 0 m). Find the electric field E(r) as a vector expressed in terms of i j and k.

What is the distance in this case? Magnitude of r? Also, how do I find the Electric field as a vector? I'm stuck..

distance=sqrt(16+9+0)=5

E=kq rvector/r^3=kq (4/64,3/27,0)
