Two parallel plates are separated by a 0.2 mm space (Figure shown below). The lower plate is stationary, the upper plate moves at a velocity of \( 5 \mathrm{~m} / \mathrm{sec} \). Estimate the shear force per unit area on the underside of the upper plate if the dynamic viscosity of the fluid is 0.001 Pa sec.
