A body with a volume of 200 cm3 is immersed in alcohol. What is the buoyancy force on the body?

Initial data: V (volume of a body immersed in alcohol; we assume that the body is completely immersed in alcohol) = 200 cm ^ 3.
Constants: ρ (density of alcohol) = 800 kg / m ^ 3, g (acceleration of gravity) = 10 m / s ^ 2.
Conversion to the SI system: V = 200 cm ^ 3 = 200 * 10 ^ -6 m ^ 3.
The buoyancy force (Archimedes force) is calculated by the formula:
Fa = ρ * g * V.
Let’s perform the calculation:
Fa = 800 * 10 * 200 * 10 ^ -6 = 1.6 N.
Answer: A buoyant force of 1.6 N. acts on a given body.
