Question: Out of the following, the only pair that does not have identical dimensions is
[ BHU 1997]
Options:
A) Angular momentum and Planck’s constant
B) Moment of inertia and moment of a force
C) Work and torque
D) Impulse and momentum
Show Answer
Answer:
Correct Answer: B
Solution:
$ \text{Moment of inertia}=mr^{2}=[M][L^{2}] $ Moment of Force = Force $ \times $ Perpendicular distance = $ [ML{{T}^{-2}}][L]=[ML^{2}{{T}^{-2}}] $
