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}}] $
