Determine the ratio of the electrostatic to the gravitational force between an electron and a proton

2. Relevant equations

I wasn't too sure where to start with this so i used the following equations:

Electrostatic force f = (charge on proton*charge on e-)/(4*pi*epsilon*d^2)

and gravitational force p = G*m1*m2/(4*pi*d^2)

where:

epsilon = 8.854187*10^-12

charge on Proton = +1 C

charge on electron = 1.6*10^-19

G = 6.67*10^-11

mass of proton = 1.6726231*10^-27

mass of e- = 9.109*10^-31

3. The attempt at a solution

then i said f/p = (1.6*10^-19)(1)/(4*pi*epsilon*d^2)/(6.67*10^-11)*(9.109*10^-31)(1.6726*10^-27)/(4*pi*d^2)

f/p = 1.414459*10^58

is this answer correct, i have a feeling im going wrong somewhere,either in my methodology or figures

any help would be much appreciated

thanks debs
