Calculate the work done in raising a stone of mass 6 kg of specific gravity to emerge in water from a depth of 4m to 1m below the surface of water

Expert Answer
Density ρs of stone is assumed as 1600 kg/m3
workdone = force × distance
force in the above equation is resultant of gravitational force and bouyancy force.
Volume V of stone, V = mass/dnsity = 6/1600 = 3.75×10-3 m3
net force = V( ρs - ρw ) g
where ρw is density of water
Workdone = V( ρs - ρw ) g × h = 3.75 × 10-3 ( 1600 - 1000 ) × 9.8 × 3 = 66.15 J
