Answer to Question #65016 in Other Physics for Helen

Question #65016
The Bohr Model of the hydrogen atom has a fixed (non-moving) proton in the nucleus
and an electron traveling around that proton in a circular orbit. The Coulomb force
between the two charges supplies the centripetal acceleration necessary to keep the
electron in circular motion. If the distance between the proton and the electron is
5.29 × 10−11 m (a value known as the “Bohr radius”), what is the tangential velocity
of the electron? The mass of an electron is 9.11 × 10−31 kg and the fundamental unit
of charge is 1.60 × 10−19 C (positive for a proton, negative for an electron).
