A thin plate $($width$=1cm)$ is pulled through a liquid between two parallel

plates separated by a distance of $0\mathrm{.}2cm.$

The density and the viscosity of the liquid are $1000k\frac{g}{m^3}$ and $1N\frac{s}{m^2},$

respectively. How much force would be needed to pull the plate at a velocity

of $1c\frac{m}{s}?$
