Q1:

One of the following statements is true with regards to bodies that float or are submerged in liquids :

A For a body wholly submerged in a liquid the stability is ensured if the centre of buoyancy is below the centre of gravity of the body

B For a body floating in a liquid the stability is ensured if the centre of buoyancy is below the centre of gravity of the body

C For a body floating in a liquid the stability is ensured if the centre of buoyancy and the centre of gravity, regardless of the relative positions of the centre of buoyancy and gravity

D For a body floating in a liquid the stability is ensured if the centre of buoyancy is below the centre of gravity and the metacentre is above both the centres of gravity and buoyancy.

ANS:D - For a body floating in a liquid the stability is ensured if the centre of buoyancy is below the centre of gravity and the metacentre is above both the centres of gravity and buoyancy.
