Asked in CBSE AIPMT 2004 · Postulates, radius, speed and angular momentum
Idea: Bohr's central postulate is that only orbits with quantised angular momentum are allowed.
The condition is mvr=(nh)/(2π), with n a positive integer.
Everything else in the model follows from it: the discrete radii, the discrete energies, and so the line spectrum.
So the assumption the model rests on is the quantisation of angular momentum.
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
