Physics And Measurement Question 237

Question: The ratio of the dimensions of Planck’s constant and that of the moment of inertia is the dimensions of

Options:

A) Time

B) frequency

C) Angular momentum

D) velocity

Show Answer

Answer:

Correct Answer: B

Solution:

[b] $ \frac{Planck’scons\tan t}{Momentofinertia}=\frac{\frac{2\pi I\omega }{n}}{I} $

$ [As\frac{nh}{2\pi }=I\omega ] $

$ =\frac{2\pi I(2\pi f)}{nI}=( \frac{4{{\pi }^{2}}}{n}.f )=[{{T}^{-1}}] $
