A schematic for a hydrogen atom is shown in the figure below. In a hydrogen atom, an electron orbits a proton. The distance between the proton and the electron is 5.3 x 10-11 m, the mass of the electron is 9.1 x 10-31 kg, the mass of the proton is 1.7 x 10-27 kg, the charge of the electron is -e, and the charge of the proton is +e, where e = 1.60 x 10- C is the fundamental charge. a) What is the electric force between the proton and the electron in a hydrogen atom? Answer: 8.2 x 10-8 N b) What is the gravitational force between the proton and the electron in a hydrogen atom? Answer: 3.7 10-47 N c) What is the ratio of the electric force, to the gravitational force, in a hydrogen atom?
