1.	flat plate is separated from a large plate by a layer of glycerine of thickness 3 xx 10^(-3)m. If the coefficient of viscosity of glycerine is 2 Ns//m^(2)what is the force required to keep the plate moving with a velocity of 6xx10^(-2)m//s. Area of the plate is4.8 xx 10 ^(-3) m
Answer» Solution :` F = ETA A dv//dx = 2 xx 4.8 xx 10 ^(-3)xx 6 xx 10 ^(-2) //3 xx 10 ^(-3)= 19 .2 xx 10 ^(-2)N`
