A cylindrical container has cross sectional area of A = 0.05 m^(2) and length L = 0.775 m. Thickness of the wall of the container as well as mass of the container is negligible. The container is pushed into a water tank with its open end down. It is held in a position where its closed end is h = 5.0 m below the water surface. What force is required to hold the container in this position? Assume temperature of air to remain constant. Atmospheric pressure P_(0) = 1 x× 10^(5) Pa, Acceleration due to gravity g = 10 m//s^(2) Density of water = 10^(3) kg//m^(3)
