1.	A square plate of 1m side moves parallel to a second plate with velocity 4m/s. A thin layer of water exist between plates. If the viscous force is 2N and the coefficient of viscosity is 0.01 poise then find the distance between the plates in mm.
Answer» SOLUTION :`F=(etaAv)/(d)impliesd=(etaAv)/(F)=(0.01xx10^(-1)xx1^(2)xx4)/(0.002)=2m`
