SCIENCE  Pls HELP

A proton (with a mass, mp = 1.673 x 10^27 kg & electrical charge, e = 1.602 x 10^19) and an electron (with a mass, me = 9.109 x 10^31 kg & electric charge e = 1.602 x 10^19) are not moving & at a distance of 1.000 x 10^10 m apart.... (assuming the electrical constant, ke = 8.988 x 10^9 Nm^2C^2 & gravitational constant, G = 6.672 x 10^11 Nm^2kg^2.
 With this info, I am required to calculate the numerical value for the magnitude of the ELECTRIC force between the proton & the electron (is this attractive or repulsive)...
 How do I calculate the GRAVITATIONAL force and state the attraction respectively?
You know it is attractive , opposite charges,
electric force = kqq/d^2
Gravitational force= G Mm/d^2
The values of k, and G are in your text.
what does the kqq/d^2 & Mm/d^2 represent with the figures at hand?
There are the equations for the coulomb force between two charges.
And the Gravitational force equation.
Both of these equations are in your text.
