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)

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