Question

Assertion :The angular momentum of the electron revolving in a stationary orbit is equal to integral multiples of $\frac{h}{2\pi }$. Reason: Angular momentum of an electron orbiting around the nucleus is quantized.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Bohr said that the angular momentum of electrons revolving in stationary orbits is quantized and it is an integral multiple of $h/2\pi$.

i.e., $mvr=\frac{nh}{2\pi }$.

Thus the correct answer is option A.
