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.
