For a floating body to be in stable equilibrium, where should its centre of buoyancy be located?

- Stable equilibrium for a floating body requires the metacenter (M) to be above the center of gravity (G). - While M above G is the primary condition for floating bodies, B above G is a sufficient condition for stability for both submerged and floating bodies. - In typical floating bodies, the center of buoyancy (B) is often below the center of gravity (G), and stability is then determined by the position of the metacenter M relative to G. - However, given the options, "Above the centre of gravity" (referring to B) is presented as a condition. If B is above G, it ensures stability.
