Question

Centre of buoyancy is -

• A. Centre of gravity of the body
• B. Centre of mass of displaced fluid
• C. Mid point between Centre of gravity and metacentre
• D. The point of intersection of buoyant force and centre line of

Answer 1

Answer:

B. Centre of mass of displaced fluid

Centre of buoyancy is the point where the centre of gravity of the displaced fluid is located. It is not the same as the centre of mass or the centre of pressure. The metacentre is the point where an imaginary vertical line passing through the centre of buoyancy and centre of gravity intersects the imaginary vertical line through a new centre of buoyancy created when the body is displaced in the fluid.
