Problem-5. A rectangular plate submerged in water is 5 m by 4 m, the 5-m side being horizontal and the4-m side being vertical. Determine the magnitude of the force on one side of the plate and the depth to its center of pressure if the top edge is (a) at the water surface; (b) 1.0 m below the water surface; (c)100 m below the water surface.
