1. Two infinitely large, flat and parallel plates are located such that they are 100mm apart, with stationary water filled in between them. A smaller flat plate, parallel to the two large plates, is located such that it is 10mm away from the bottom plate. An external force is then exerted on the small plate such that it moves with a velocity of 200mm/s parallel to the two large plates. If the small plate measures 750mm by 34 mm and linear velocity variation in the water can be assumed during the motion, calculate the force exerted on the small moving plate by the water. [Dynamic viscosity of water = 1.1 x 10Pa.s] [Ans: 6.23 x 10N] 1.
