Question

Which is the main postulate of Bohr’s model of atom in the following (A) Protons are present in the nucleus (B) Electrons are revolving around the nucleus (C) Centrifugal force produced due to the revolving electrons balances the force of attraction between the electron and the protons (D) Angular momentum of electron is an integral multiple of (h/2 π )

The electron can move only in those circular orbits where the angular momentum is a whole number multiple of (h/2 π ) or it is quantised.

Q. Which is the main postulate of Bohr’s model of atom in the following

Protons are present in the nucleus

Electrons are revolving around the nucleus

Centrifugal force produced due to the revolving electrons balances the force of attraction between the electron and the protons

Angular momentum of electron is an integral multiple of $\frac{h}{2 π}$

The electron can move only in those circular orbits where the angular momentum is a whole number multiple of $\frac{h}{2 π}$ or it is quantised.
