A balloon filled with hydrogen has a volume 1m^(3) and its mass is 1Kg .Find the volume of a block of light material which it can just lift (in m^(3) ): [ density of block =91.3kg/m^(3) and that of air =1.3kg/m^(3)]

A balloon filled with hydrogen has a volume of 1m^(3) and its mass is 1kg . What would be the volume of the block of a very light material which it can just lift ?

A balloon filled with hydrogen has a volume of 1000 litres and has mass of 1kg. What would be the volume of the block of very light material which it can just lift? One litre of the material has a mass 91.3g and density of air is 1.3 g" ""litre"^(-1).

If the density of a block is 981 kg//m^(3) then it shall
