For the stable equilibrium of a floating body, the centre of gravity (G) must:

An object floats in a liquid with half of its volume submerged. What is the magnitude of the buoyant force acting on the object?

The volume of a small ball is calculated to be 25 cm3 and it weighs 30 g in air. Will this ball float or sink in pure water (density = 1 g/cm3)?
