4. A rectangular tank water (width 14.0m, length 14.0m, and height 20 m) is filled with water and open to the atmosphere. The water level in the tank is 1 m below the top of the tank. This tank sits upon a platform of height h. If the water tank is plugged at the bottom so no water is flowing, what is the resultant force exerted by the water on the bottom face of the container? What is the resultant...
