$($b$)$ A fluid with viscosity $0\mathrm{.}07N\frac{s}{m^2}$ flowing between two parallel plates. The lower plate is

stationary and the upper plate is moving with a velocity of $8\frac{m}{s}$ in positive $x-$direction. The two

plates are separated by $2$ m $.$

Draw the schematic representation of the problem statement and Calculate the Shear Stress.
