Question $4(1$ point$)$

The Newtonian fluid shown is confined between the plate and a fixed surface as shown in the figure below.

The plates has a surface area of $25{10}^{3}m{m}^2$ in contact with the fluid.

Take $$ as the viscosity of the fluid and suppose that $h$ is the distance between the plate and a fixed surface mm $.$

Determine the shear stress that the fluid exerts on the top moving plate.
