Question

Dimensional formula of angular velocity is

• A. $\left[L^{-1}{T}^{-1}\right]$
• B. $\left[L{T}^{-2}\right]$
• C. $\left[L^0{T}^{-1}\right]$
• D. $\left[L{T}^{-1}\right]$

Answer 1

Answer: (C)

$[\omega ]=\left[\frac{v}{r}\right]=\frac{L{T}^{-1}}{L}=T^{-1}\Rightarrow [\omega ]=L^0{T}^{-1}$
