A 1.5 cm wide gap between two vertical plane surfaces is filled with an oil of specific gravity 0.85 and dynamic viscosity 2.0 Ns/m". A metal plate 1.0 m x 1.0 m x 0.1 cm thick and weighing 20 N is placed midway in the gap as shown in Fig. 1. Find the force required if the plate is to be lifted up with a constant velocity of 0.2 m/s.
