Question: The dimensions of surface tension are...

The dimensions of surface tension are

A

ML1T2ML^{- 1}T^{- 2}

B

MLT2MLT^{- 2}

C

ML1T1ML^{- 1}T^{- 1}

D

MT2MT^{- 2}

Answer

MT2MT^{- 2}

Explanation

Solution

Surface tension

= ForceLength=[MLT2]L=[MT2]\frac{\text{Force}}{\text{Length}} = \frac{\lbrack MLT^{- 2}\rbrack}{L} = \lbrack MT^{- 2}\rbrack
