Homework Statement



if a proton and a electron put in a gravitational field, what is their ratio compare to one another?

Homework Equations


fg= GMm/r^2
mass of a proton = 1.67 x 10^-27 kg
mass of a electron= 9.11 x 10^-31 kg

The Attempt at a Solution



i tried to divided them out, i got 1 to 1800, not sure if it is right

If in a gravitational field of strength 'g', the force on any mass in that field is mg.

So the force on the mass of the proton is 1.67(10-27)g. Find the force on the electron and then divide.
