1. 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
2. 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
3. For a body floating in a liquid the stability is ensured if the centre of buoyany and the centre of gravity, regardless of the relative positions of the centre of buoancy and gravity
4. 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
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
