  1. Question 1

    Q1. A sphere of radius 0.1 m is fully submerged in water. What is the buoyant force?

    • A) 4.1 N
    • B) 41 N
    • C) 4.1 x 10^1 N
    • D) 4.1 x 10^2 N

    Answer: 41 N

    Explanation: Buoyant force = ρVg = 1000 kg/m³ * (4/3)πr³ * 9.8 m/s² = 41 N; correct application of Archimedes' principle.
