    A long time ago in a galaxy far far away there was a planet that had two moons: Dawsonia and Panaside. Panaside was located in a stable circular orbit 2398 km from the surface of the planet, had an orbital period of 19 hours, and was a magnificent moon which served as the intellectual center of the whole sector. The other moon - Dawsonia - was a considerably smaller body which had no intelligent life. Dawsonia was in a stable...

    Say you have a point charge of one Coulomb and a hydrogen atom some distance away. Within what distance would the difference of forces on the proton and electron from the Coulomb charge exceed the attraction between the proton and electron that holds the hydrogen atom together. Treat the hydrogen atom as a proton and electron 0.53 × 10−10 m (a.k.a., one Bohr radius) apart

    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.

    This is a challenging multi-step problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! The Bohr model correctly predicts the main energy levels not only for atomic hydrogen but also for other "one-electron" atoms where all but one of the atomic electrons has been removed,...
