Homework Help: Physics

Could someone help me on how to put this all together.
Atomic physicists ignore the effect of gravity within an atom. To see why, calculate and compare the gravitational and electrical forces between an electron and a proton separated by 10-10m.

Im confused ok i have that the mass of a proton is 1.6726231 x 10^-27 and the mas of an electron is 9.1093897 x 10^-31
charge of an electron is 1.602 x 10^-19 what do i do with all of this, is g1 the charge of the proton g2 the charge of the electron? what is d is that 10 m?

You have the masses right. The charge on the proton is the same as the electron, but opposite charge.

d is 10^-10 meters.
