32. The dimensional formula for angular momentum is
[1988]
(a) $[M^{0} L^{2} T^{-2}]$
(b) $[ML^{2} T^{-1}]$
(c) $[MLT^{-1}]$
(d) $[ML^{2} T^{-2}]$
Show Answer
Answer:
Correct Answer: 32.(b)
Solution:
- (b) Angular momentum
$=$ Momentum of inertia $\times$ Angular velocity
So dimensional formula,
$=[ML^{2}] \times[T^{-1}]$
$=[ML^{2} T^{-1}]$
