How do the gravitational and electrical forces between a proton and neutron compare

Assume distance of seperarion is 1m

F. elec = kQq/r^2

charge of a proton: 1.6*10^-19 C

charge of a neutron: 0 C

F. elec = 0 N

F. grav = GMm/r^2

mass of a proton: 1.672621898*10^-27 kg

mass of a neutron: 1.674927471*10^-27 kg

F. grav = (6.67408*10^-11) * (1.674927471*10^-27) * (1.672621898*10^-27) : (1^2)

F. grav = 1.8699588*10^-64 N
