Units And Dimensions Question 1
Question 1 - 2024 (01 Feb Shift 1)
The dimensional formula of angular impulse is :
(1) $\left[ML^{-2} T^{-1}\right]$
(2) $\left[ML^{2} T^{-2}\right]$
(3) $\left[MLT^{-1}\right]$
(4) $\left[ML^{2} T^{-1}\right]$
Show Answer
Answer: (4)
Solution:
Angular impulse $=$ change in angular momentum.
[ Angular impulse $]=[$ Angular momentum $]=[mvr]$
$=\left[ML^{2} T^{-1}\right]$
