Physics Question on Units and measurement

Which one of the following represents the correct dimensions of the coefficient of viscosity?

A

ML−1T−2ML^{-1}T^{-2}

B

MLT−1MLT^{-1}

C

ML−1T−1ML^{-1}T^{-1}

D

ML−2T−2ML^{-2}T^{-2}

Answer

ML−1T−1ML^{-1}T^{-1}

Explanation

Solution

Dimensions of ?? (coefficient of viscosity) =MLT−2M0L0.M0LT−1=ML−1T−1= \frac{MLT^{-2}}{M^{0}L^{0}.M^{0}LT^{-1}} = ML^{-1}T^{-1}
