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:
[tex]F=k_e \frac {Q_1 Q_2} {r^2}[/tex]

I got 0.15 N, in the +y direction

That equation will not help you. There is an equation relating the force felt by a charge in an electric field to the magnitude of the charge and the magnitude of the electric field. In your class, it may have been called the Lorentz force law. Does that help?
