Two cylinders, one made of lead (density 11,340 kg/m³) and one of copper (density 8,940 kg/m³), have the same radius and height. They are thrown into a pool of water (density 1,000 kg/m³) and sink to the bottom. As they are sinking, describe the buoyant forces on the cylinders. A) The buoyant force on the lead cylinder is greater than that on the copper. B) There is no buoyant force on either, as they are sinking. C) The buoyant force on the copper cylinder is greater than that on the lead. D) The buoyant force is the same on each cylinder.

Question

Quizplus · Accepted Answer

The buoyant force depends on the volume of fluid displaced by an object, not its material. Since both cylinders have the same size and shape, they displace the same volume of water and experience the same buoyant force.
