The body on which the Archimedean force of 400N acts is immersed in water, what is the volume of this body.

To calculate the value of the volume of a body immersed in water, we will use the formula: Fa = ρw * g * V, whence V = Fa / (ρw * g).

Variables and constants: Fa – the magnitude of the Archimedean force (Fa = 400 N); ρw – water density (ρw = 1000 kg / m3, fresh water); g – acceleration due to gravity (g ≈ 10 m / s2).

Calculation: V = Fa / (ρw * g) = 400 / (1000 * 10) = 40 dm3 (0.04 m3).

Answer: The volume of a body immersed in water is 40 dm3.
