Question

The dimensional formula for areal velocity is

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

Answer 1

Answer: (C)

Areal velocity is the area covered per unit time.
$\because \left[Area\right]=[L^2]$
$\therefore \left[Arealvelocity\right]=[L^2{T}^{-1}]$
