Assertion : Planck's constant (h) represents angular momentum.
Reason : Because, both have the same dimension , `[M^1 L^2 T^(-1)]`

A

If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.

B

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

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
(a)
Dimensions of `h = (E )/(v) = (ML^2 T^(-2))/(T^(-1))`
`=M^1 L^2 T^(-1)`
which are same as the dimensions of angular momentum.
