The earth revolves around the sun in an orbit of radius 1.5 × 10¹¹ m with orbital speed 30 km/s. Find the quantum number that characterises its revolution using Bohr's model in this case (mass of earth = 6.0 × 10²⁴ kg).

TextQuantization of Angular Momentum and Orbital Motion in Bohr ModelCBSE PYQ

In Bohr model of hydrogen atom, find the ratio of period of revolution of the electron in the orbit n = 2 to that in the orbit n = 1.

The ratio of the magnitude of magnetic moment to that of angular momentum, of an electron revolving around the nucleus in a hydrogen atom is :
