Consider a thin square plate floating on a viscous liquid in a large tank. The height

h

of the liquid in the tank is much less than the width of the tank. The floating place is pulled horizontally with a constant velocity

{\mu _{0.}}

Which of the following statements is (are) true?

A
The resistive force of liquid on the plate is inversely proportional to $h$
B
The resistive force of liquid on the plate is independent of the area of the plate
C
The tangential (shear) stress on the floor of the tank increases with ${\mu _0}$
D
The tangential (shear) stress on the plate varies linearly with the viscosity $\eta$ of the liquid
