Question

Forces in FluidLet us assess1.The weight of a piece of stone in air is 120 N and its weight inwater is 100 N. Calculate the buoyancy experienced by the stone.A body, which floated in water, sank when put in kerosene. Whydid it happen?Observe the figures of an object placed in different liquids.II111111111IIIIIIIIIIIIIIIIIIIIII)IIIIIIIIIIIIIIIIIIIIIIIIVIIIIIIIIIIIILIIIIIIIIIIUITIIIIIIIVIILILITLIETUVIIIMULTILIUIIIIIIIIIIIIIIIIIIIIIIIIIMIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII)TUILUULITILIULUITITUITIIULITTULLIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII1)TITUTIITI11TIUTILILiquid ALiquid Ba.Compare the gravitational force and the buoyancy acting onthe body when it is in the liquids A and B.Among A and B, which is the liquid whose density is greaterthan that of the object? Why?b.​

Answer 1

120 N - 100 N = 20 N ( buoyancy)
