Asked in CBSE AIPMT 1989 · Postulates, radius, speed and angular momentum
Idea: Bohr's stationary orbits are defined by a condition on angular momentum, not on energy.
The postulate is that an electron can occupy only those orbits for which mvr is an integer multiple of h/(2π).
In such an orbit the angular momentum is constant and the electron does not radiate.
So the conservation law the model is built on is that of angular momentum.
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
