A ball has a mass of 0.50 kg and a volume of 1.3 × 10⁻³ m³. The ball is floating in equilibrium on still water. The two forces that act on the ball are its weight and the upthrust due to the water. The density of the water is 1.0 × 10³ kg m⁻³. What is the percentage of the volume of the ball above the surface of the water?
