answered-by-expert Expert Answer
Centre of gravity of the object is the point through which gravitational force is acting. Centre of buoyancy is the centre of gravity of diplaced liquid when an object is floating in liquid.. Center of gravity and centre of buoyancy will be in vertical line (line of action of gravitationl force) as shown in figure.
 
When the object is partially immersed, centre of buoyancy is below centre of gravity. When the object is fully immersed, center of gravity and centre of buoyancy coincide
