Consider an electron with charge āe and mass m orbiting in a circle around a hydrogen nucleus (a single proton) with charge +e. in the classical model, the electron orbits around the nucleus, being held in orbit by the electromagnetic interaction between itself and the protons in the nucleus, much like planets orbit around the sun, being held in orbit by their gravitational interaction. when the electron is in a circular orbit, it must meet the condition for circular motion: the magnitude of the net force toward the center, f_c, is equal to mv^2/r. given these two pieces of information, deduce the velocity v of the electron as it orbits around the nucleus. express your answer in terms of e, m, r, and epsilon_0, the permittivity of free space.
