SUMMARY
The discussion focuses on calculating the gravitational force of attraction between a proton and an electron fixed at a distance of 2.8 meters. The gravitational constant, G, is specified as 6.67 x 10^-11 N(m/kg)^2. The correct formula to use for gravitational force is F = GMm/r², where M is the mass of the proton (1.67 x 10^-27 kg) and m is the mass of the electron (9.11 x 10^-31 kg). The participants clarify the application of gravitational force in contrast to electric force, emphasizing the need to use the appropriate constants and formulas.
