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)`

Answer

250 N
