Physics

Suppose that an electron and a proton are placed at a distanceof 1.2nm away from each other (about 10 times the radius of ahydrogen atom).
(a) How much is the Coulomb force between the electron and theproton?
(b) Under this Coulomb force alone, how much is the accelerationof the electron towards the proton (in m/s2 )? (Google for themissing information.)
(c) If the electron is instead placed on the edge of thesupermassive black hole Sagittarius A* (about 22 million km awayfrom the center), how much is the gravitational acceleration ofelectron towards the black hole (in m/s2 )? (Google for the missinginformation about Sagittarius A*.)
(d) For this electron, how does the gravitational influence ofthe black hole compare to the electric influence of the proton?
