When a body, floating in a liquid is given a small angular displacement, it starts oscillating about a point known is Correct Answer Meta centre

Concept:

Meta Centre is defined as the point about which a body starts oscillating when body is tilted by a small angle. The meta-centre may also be defined as the point at which the line of action of the force of buoyancy will meet the normal axis of the body when the body is given a small angular displacement.

The distance MG i.e. the distance between the meta-centre of a floating body and the centre of gravity of the body is called meta-centric height. It is measured along the line BG.

The stability of a floating body is determined from the position of Meta-centre (M).

Stable Equilibrium: If the point M is above G, the floating body will be in stable equilibrium.

Unstable Equilibrium: If the point M is below G, the floating body will be in unstable equilibrium.

Neutral Equilibrium: If the point M is at the centre of gravity of the body, the floating body will be in neutral equilibrium.
