A bottle has a thin nozzle on top. It is filled with water, held horizontally at a height of 1 m and squeezed slowly by hands so that the water jet coming out of the nozzle hits the ground at a distance of 2m . If the area over which the hands squeeze it is `10 cm^2.` the force applied by hand is close to (take g= 10 `m//s^2` and density of water= 1000 `kg//m^3` )
