Answer

Centre of buoyancy B, is the centre of gravity of the displaced liquid.

The centre of buoyancy B, and centre of gravity G, will coincide if the body is fully immersed in the liquid.

In the case when the body is partially above and partially below the surface of liquid, the centre of buoyancy B is vertically below the centre of gravity G.

A weather forecasting plastic balloon of volume 15 m3 contains hydrogen of density 0.09 kg m-3. The volume of an equipment carried by the balloon is negligible compared to it’s own volume. The mass of the empty balloon alone is 7.15 kg. The balloon is floating in air of density 1.3 kg m-3. Calculate : (i) the mass of hydrogen in the balloon, (ii) the mass of hydrogen and balloon, (iii) the total mass of hydrogen, balloon and equipment if the mass of equipment is x kg, (iv) the mass of air displaced by balloon and (v) the mass of equipment using the law of floatation.
