The body weighs 6H in air and 4H in water. What is the volume of this body?

To calculate the volume of a taken body, you can use the equality: Pair – Pw = Fa = ρw * g * V, whence we express: V = (Pair – Pw) / (ρw * g).

Variables and constants: Pair – weight in air (P1 = 6 N); Рв – weight of water (Р2 = 4 N); ρw is the density of water (ρw = 1000 kg / m3); g – acceleration due to gravity (g ≈ 10 m / s2).

Calculation: V = V = (Pair – Pw) / (ρw * g) = (6 – 4) / (1000 * 10) = 0.0002 m3 = 0.2 dm3.

Answer: The volume of the taken body is 0.2 dm3.
