2 Atomic Physics The Rutherford model of an atom asserts that electrons move in circular or elliptical orbits about the nucleus They are held in orbit by the Coulomb force. In hydrogen a single electron moves in a circular orbit around a single proton. The radius of a hydrogen atom is 5.3. 10-1 m a) What is the Coulomb force between the proton and the electron? (b) What is 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...
5) (2090) The electron is bound to the proton in a hydrogen atom due to the Coulomb force. Now assume that electric charge did not exist and the electron was bound to the proton by the gravitational force to form a hydrogen atom, please derive the corresponding expressions for (a) (8%) the Bohr radius ao and (b) (7%) energy En, (c) (5%) Compute the smallest frequency of the Balmer series.

In a simplistic model of the hydrogen atom, the electron orbits the proton in a circle of radius 53 pm. What is the orbital period of the electron, in seconds, if the force responsible for the proton-electron attraction is electric?
E18M.6 The Rutherford model of the hydrogen atom (pro- posed by Ernst Rutherford in roughly 1910) imagines the electron as orbiting the proton in a circle (a) Use Newton's second law, Coulomb's law, and what you know about acceleration in circular motion to show that the electron's acceleration in a circular orbit of radius r is ã/(4me,mr) and its orbital kinetic energy is K-72/ (8πεο r), where e is the proton's charge and m is the electron's mass. (b) Show...
An electron with charge −e and mass m moves in a circular orbit of radius r around a nucleus of charge Ze, where Z is the atomic number of the nucleus. Ignore the gravitational force between the electron and the nucleus. Find an expression in terms of these quantities for the speed of the electron in this orbit. (Use any variable or symbol stated above along with the following as necessary: k for Coulomb's constant.) v = ?
In an early model of the hydrogen atom (the Bohr model), the electron orbits the proton in uniformly circular motion. The radius of the circle is restricted (quantized) to certain values given by r = n^2a_0, for n = 1, 2, 3, ..., where a_0 = 52.92 pm. What is the speed of the electron if it orbits in (a) the smallest allowed orbit and (b) the seventh smallest orbit? (c) If the electron moves to larger orbits, does its...
