A sphere of radius 0.1 m is fully submerged in water. What is the buoyant force?
Q1. A sphere of radius 0.1 m is fully submerged in water. What is the buoyant force?
Answer: 41 N
Explanation: Buoyant force = ρVg = 1000 kg/m³ * (4/3)πr³ * 9.8 m/s² = 41 N; correct application of Archimedes' principle.
