Physics And Measurement Question 53
Question: Dimensional formula for angular momentum is
[CBSE PMT 1988, 92; Pb. PET 2000]
Options:
A) $ ML^{2}{{T}^{-2}} $
B) $ ML^{2}{{T}^{-1}} $
C) $ ML{{T}^{-1}} $
D) $ M^{0}L^{2}{{T}^{-2}} $
Show Answer
Answer:
Correct Answer: B
Solution:
Angular momentum = $ mvr $
$ =[ML{{T}^{-1}}][L]=[ML^{2}{{T}^{-1}}] $
