Units of surface tension and viscosity are-

Options

A. `kg*m^(-1)*s^(-1),N*m^(-1)`
B. `kg*s^(-2),kg*m^(-1)*s^(-1)`
C. `N*m^(-1),kg*m^(-1)*s^(-2)`
D. `kg*s^(-1),kg*m^(-2)*s^(-1)`

Answer

B

Explanation

Surface tension `=("Force")/("Length")=(N)/(m)=((kg*m*s)^(-2))/(m)=kg*s^(-2)`.
Coefficent of viscosity`=N*m^(-2)*s=kg*ms^(-2)*m^(-2)*s^(-1)`
