Question

In a large container that is initially empty, a solid aluminum cylinder hangs by an ideal spring. The cylinder is 52.5 mm long and 30.0 mm in diameter. The spring is stretched 42.0 mm by the cylinder. The container is then filled with a liquid of unknown density, causing the cylinder to rise by 11.8 mm. What is the buoyant force of the liquid acting on the cylinder, given that the mass density of aluminum is 2720 kg/m3?
