The fundamental quantity which has the same power in the dimensional formula of surface tension and coefficient of viscosity is

Options

A. Mass, speed and energy are scalars
B. Length
C. Time
D. None

Explanation

surface tension `=(F)/(l)=M^(1)L^(0)T^(-2)`
viscosity, `n=(Fxx x)/(A xx v)=M^(1)L^(-1)T^(-1)`
