An electron and a proton are separated by a distance of 1.6×10^−10 m (roughly the diameter of a single atom). The masses of the electron and proton are me=9.11×10^−31 kg and mp=1.673×10^−27 kg, respectively. The elementary charge e=1.602×10^−19 C. The universal gravitational constant G=6.67×10−11 N·m^2/kg^2 and the coulomb constant ?=8.988×10^9 N·m^2/C^2.
