Question

In order that a floating object be in stable equilibrium, its centre of buoyancy ________.

• A. should be vertically below its centre of gravity
• B. should be horizontal, in line with its centre of gravity
• C. should be vertically above its centre of gravity
• D. may be anywhere

Answer 1

The correct option is C should be vertically above its centre of gravity

For stable equilibrium, the center of gravity should be below its center of buoyancy. Otherwise, the net torque will be in direction of angular-displacement.
