An interesting (but oversimplified) model of an atom pictures an electron "in orbit" around a proton. Suppose this electron is moving in a circular orbit of radius 0.13 nm (1.3 Times 10^-10 m) and the force that makes this circular motion possible is the electric force exerted by the proton on the electron. Find the speed of the electron.

In the Bohr model of the Hydrogen atom, a single electron orbits around a single proton (which constitutes the nucleus). The mass of the electron (9.11x10-31 kg) is much less than the proton (1.67x10-27 kg), so the proton remains stationary while the electron moves around it. If the electron is 6.6x10-11 m away from the proton, calculate the magnitude of the electric force (in N) exerted by the proton on the electron. b) [Continued ...] In the Bohr model, an...
