Obviously I have to use Coulomb's law. I am not sure how to integrate the masses of each object into the equation. The answer will be in Newtons. Since they are both positive charges they will be accelerating away from each other.

The separation distance is squared in Coulomb's Law.

Do you know Newton's law of universal gravitation ? It looks much like Coulomb's Law, with the masses replacing the charges. The constants are very different.
