(a) What is the magnitude of the electric force between the proton and the electron? (b) What is the magnitude of the electric field due to the proton at r? -31, -27, (c) Given that the mass of the electron is m, =9.1x10"kg and the mass of the proton is m, =1.7x10 kg. what is ratio of the magnitudes of the electrical and gravitational force between electron and proton? Does the result depend on the distance between the proton and the electron? (d) In light of your calculation in (b), explain why electrical forces do not influence the motion of planets.
