(b) Two large plane surfaces are 2.8 cm apart. The space between the surfaces is filled with glycerine. What force is required to drag a very thin plate of surface area of 0.6 m² between the two large plane surfaces at a speed of 1.5 m/s, if (i) The thin plate is in the middle of the two plane surfaces, and (ii) The thin plate is at a distance of 0.7 cm from one of the plane surfaces? Assume the kinematic viscosity of glycerine is 1.19×103 m²/s. (15 marks)
