SATHEE: Physical World Units and Measurements

Physical World Units and Measurements - Result Question 36

38. The dimensional formula for angular momentum is

(a) $[M^{0} L^{2} T^{- 2}]$

(b) $[M L^{2} T^{- 1}]$

(d) $[M L^{2} T^{- 2}]$

[1988]

Show Answer

Answer:

Correct Answer: 38. (b)

Solution:

(b) Angular momentum

$=$ Momentum of inertia $\times$ Angular velocity

So dimensional formula,

$= [M L^{2}] \times [T^{- 1}]$

$= [M L^{2} T^{- 1}]$
