What is center of buoyancy? State it's position for a floating body with respect to the centre of gravity of body.
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.
