Question

The centre of buoyancy of a floating object is

• A. at the centre of gravity of the object.
• B. at the centre of gravity of the submerged part of the object.
• C. at the centre of gravity of the remaining part outside the fluid of the object.
• D. at the centre of gravity of the fluid displaced by the submerged part of the object.

Answer 1

The correct option is D at the centre of gravity of the fluid displaced by the submerged part of the object.

Figure shows the points described in the question. C.G. of submerged part of the object will be at the centre of buoyancy if the object is uniform, Otherwise shifts from this point. From figure (D) is correct.
