I need the answer as soon as possible

Extracted text: Two plates are kept separated by a film of oil of 0.025 mm. the top plate moves P.1.1 with a velocity of 50 cm/s while the bottom plate is kept fixed. Find the fluid viscosity of eil if the force required to move the plate is 0.2 kg/m. Ans. u= 9.81x10 Pa.s ?
