I tried everything but my answer keeps coming out wrong. I get the direction but not the magnitude 
Anyone know how to solve it?
The nucleus of an atom has a charge of 79 protons.
(a) What are the direction and magnitude of the electric field at 3.0 X 10 ^ -10 m from the nucleus?
(b) What are the direction and magnitude of the force exerted on an electron located at this distance?
