Q. The expression $\lbrack ML^{- 1}T^{- 1}\rbrack$ represents
A) Momentum
B) Force
C) Pressure
D) Coefficient of viscosity
Explanation
Coefficient of viscosity $= \frac{F \times r}{A \times v} = \frac{\left\lbrack MLT^{- 2} \right\rbrack \times \lbrack L\rbrack}{\left\lbrack L^{2} \right\rbrack \times \lbrack LT^{- 1}\rbrack}$ $= \lbrack ML^{- 1}T^{- 1}\rbrack$
