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 m^2 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 ofglycerine is 1.19×10^-3 m^2/s
