A plate of area 500 cm^2 is lying on the layer of oil of thickness 3mm. Calculate the horizontal force required to move the plate with a constant velocity of 5 cm/sec. Coefficient of viscosity of oil is 1.9 Ns m^-2

then what will be the new terminal velocity ? Two identical water drops are falling down in the air with a terminal velocity v. If the two drops combine and from a single drop
