A metal plate of area 2m^2 is pulled horizontally with a velocity of 0.5m^-1 on a liquid layer 1mm thick. The force required, if the viscosity of liquid is 12Nsm^-2 is

If C (2n,3) : C ( n,2)=12 : 1 find n,

A metal plate of area 10^(-3)m^(2) is placed on a liquid layer of thickness 0.8mm . The coefficient of viscosity of that liquid is 24 poise .Then the horizontal force required to move the plate with a velocity of 1cms^(-1) .

Aflat plate of area 0.05 m^(2) is separated from another large plate at rost by a liquid layer of uniform thickness 1mu m . The tangential force needed to move the smaller plate with a constant velocity of 10 cm s ^(-1) i s 20 N. Calculate the coefficent of viscosity of the liquid.
