The height to which a cylindrical vessel is to be filled with a homogenous liquid, presses the side of the vessel equal to the force exerted by the liquid on the bottom of the vessel, is equal to

A horizontal jet of water coming out of a pipe of area of cross-section 20cm^(2) hits a vertical wall with a velocity of 10ms^(-1) and rebounds with the same speed. The force exerted by water on the wall is .
