A large tank is filled waith water (density = 10^(3) kg//m^(3) ). A small hole is made at a depth 10 m below water surface. The range of water issuing out of the hole is R on ground. Approximately what extra pressure must be applied on the water surface so that the range becomes 2R (take 1 atm = 10^(5) Pa and g = 10 m//s^(2) )

The range of water flowing out of a small hole made at a depth 10 m below water surface in a large tank is R . Find the extra pressure (in atm) applied on the water surface so that range becomes 2R . Take 1atm=10^(5)Pa .

A tank is filled by water ( rho = 10^3 kg//m^3 ). A small hole is made in the side wall of the tank at depth 10 m below water surface. A water jet emerges horizontal from the hole and falls at horizontal distance R from it. The amount of extra pressure (in terms of atmospheric pressure) that must be applied on the water surface, so that range becomes 3R on the on the ground will be (cross section area of hole is negligible and 1 atm = 105 Pa, g = 10 m/ s^2 )
