Someone please help me, I am having the worst time understanding this problem. Where do I begin?

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.

    Ok, do it

    Fe= kqq/d^2

    Fg=GMm/d^2

    I will be happy to critique your thoughts.

    I will be happy to critique your thoughts. You knwo the charge on an electron/proton for the electrical force, and you know the masses for the gravitational force.

    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?

  • Physics -

    what? i know the masses yes not sure about the charge. . . but the fromula i have is f=k g1f2/r^2 so And all these numbers are something to the power of something else how do i work that out?

  • Physics -

    You have the charges right. Now use your calculator to solve each. Your text will give you the value of G, and k.
