Problem
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 plate is pulled horizontally with a constant velocity μ0. Which of the following statements is (are) true? [Adv. 2018]
(1) The resistive force of liquid on the plate is inversely proportional to h
(2) The resistive force of liquid on the plate is independent of the area of the plate
(3) The tangential (shear) stress on the floor of the tank increases with μ0
(4) The tangential (shear) stress on the plate varies linearly with the viscosity η of the liquid
