Question

A small thin plane surface is pulled through the liquid filled space between two large horizontal planes in the parallel direction. Show that the force required will be minimum if the plate is located midway between the planes. (Take the area of the plate as 1 m² and h = 0.1 and velocity as 1 m/s and find force for h = 0.1m, 2m, 0.3m, 0.4m, 0.5, 0.6m from the bottom )
