# Coulomb Law

I need help with this problem.

What is the magnitude and direction of the elctric force on a -1.2 micro Coulomb charge at a point where the electric field is 2500 N/C and is directed along the +y axis?

It has something to do with this equation:
$$F=k_e \frac {Q_1 Q_2} {r^2}$$

I got 0.15 N, in the +y direction
