A metal plate of area `10^(3)" "cm^(2)` rests on a layer o oil 6 mm thick. A tangential force of `10^(-2)` N is appled on it to move it with a constant velocity of 6 cm `s^(-1)` . The coefficient of viscosity of the liquid is :-

A metal plate ofarea 100 sq. cm, rests on a layer of oil 2mm thick. A force of 0.1 N applied parallel to the plate horizontally keeps it moving with uniform speed of 1cm/ s. What is the coefficient of viscosity of oil ?

A metal plate of area 5 cm ^(2) is placed on a 0.5 mm thick castor oil layer .If a force of 22,500 dyne is needed to move the plate with a velcity of 3cms^(-1) Calculate the coeffcient of viscosity of castor oil.

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.

A metal plate of area 500 cm^92) is kept on a horizontal surface with a layer of oil of thickness 0.5 mm between them. The horizontal force required to drag the plate with a velocity of 2 cm/s is (coefficient of viscosity =0.9 kg/ms)
