The dimensional formula for areal velocity is

The dimensional formula for areal velocity is

Options

  1. A[M0L−2T][ M^{0}L^{- 2}T ]
  2. B[M0L−2T−1][ M^{0}L^{- 2}T^{- 1} ]
  3. C[M0L2T−1][ M^{0}L^{2}T^{- 1} ]
  4. D[M0L2T][ M^{0}L^{2}T ]

Correct answer

C. [M0L2T−1][ M^{0}L^{2}T^{- 1} ]

Step-by-step solution

Areal velocity is the area covered per unit time.

∵[Area]=[L2]∵ \left[Area\right] = [ L^{2} ]

∴[Arealvelocity]=[L2T−1]∴ \left[Arealvelocity\right] = [ L^{2}T^{- 1} ]
