A problem when trying to compare electromagnetism with gravity

[QUOTE="mjc123, post: 6508858, member: 610180"] You are not comparing like with like. The correct comparison for a Bohr atom would be with an object in low Earth orbit. For an orbiting object, PE = -2KE and total energy = -KE; escape energy = KE. KE of the orbiting object is half that of an object freely falling from infinity to the orbital radius. Simply dropping an object from infinity won't cause it to go into orbit; you have to lose some of that energy somehow (e.g. the proton-electron system you describe has total energy 0, while a Bohr atom has energy -13.6 eV, PE -27.2, KE +13.6).
