  1. Question 1

    Q1. A body weighs 50 N in air and 40 N in water. What is the volume of the body?

    • A) 1.02 x 10^-3 m³
    • B) 1.02 x 10^-2 m³
    • C) 1.02 x 10^-1 m³
    • D) 1.02 m³

    Answer: 1.02 x 10^-3 m³

    Explanation: V = (W_air - W_water) / ρg = (50 N - 40 N) / (1000 kg/m³ * 9.8 m/s²) = 1.02 x 10^-3 m³; correct application of Archimedes' principle.
