A movable plate is at a height 0.05 mm above a fixed plate. The separation between the plates is filled with a fluid. The top layer of the fluid moves at a speed of 100 cm s 1 (thus, the moyable plate moves at this same speed). A force of 2 N per unit area is required to maintain this speed. Assuming the flow of the fluid is laminar and the change in velocity of the fluid is constant, determine the coefficient of viscosity of the fluid.
