Question

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 u₀. 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 u₀
(D) The tangential (shear) stress on the plate varies linearly with the viscosity η of the liquid

Answer 1

Answer:

A , C and D are correct

Hopefully understandable ^-^
