(A) bohr's third postulaate states that the stationary orbits are those for which the angular momentum is some integral multiple of `(h)/(2pi)`.
(R) linear momentum of the electron in the atom is quantised.

A

if both assertion and reason are true and reason is the correct explanation of assertion.

B

if both assertion and reason are true but reason is not the correct explanation of assertion.

C

if assertion is true but reason is false.

D

if both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
bohr's second postulate states that the stationary orbits are those for which the angular momentum is some integral multiple of `(h)/(2pi)`i.e.`L=n(h)/(2pi)` where n is an integer called a quantum number. But linear momentum is not quantised.
