Assertion(A): If a particle moves with a constant velocity, then angular momentum of this particle about any point remains constant.

Reason(R): Angular momentum has the units of Planck's constant.

View answer and explanation

Correct option: B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.

Option B is correct because both Assertion and Reason are correct, but the Reason is not the correct explanation of Assertion. Angular momentum is constant when velocity is constant, and angular momentum has the units of Planck's constant.
