A 1.5-kg aluminum cylinder with a density of 2700 kg/m³ is at the bottom of a pool. The force acting on the cylinder from the floor of the pool is

Question

Quizplus · Accepted Answer

The buoyant force on the cylinder is equal to the weight of the water displaced by the cylinder. The volume of the cylinder is mass/density = 1.5 kg / 2700 kg/m³ = 0.0005556 m³. The buoyant force is the volume times the density of water (1000 kg/m³) times gravity (9.8 m/s²), which equals 5.44 N. The weight of the cylinder is 1.5 kg * 9.8 m/s² = 14.7 N. The force from the floor is the weight minus the buoyant force: 14.7 N - 5.44 N = 9.26 N, approximately 9.3 N.
