Question

When does a body float in a liquid?

Answer 1

Archimedes principle:

1. This principle states that the upward buoyant force produced on a fully or partially submerged body is equivalent to the fluid's weight that the body displaces and operates throughout the upward orientation at the displaced fluid's center of mass.
2. The tendency of an item to float in a fluid is referred to as buoyancy.
3. In the existence of gravity, all liquids and gases generate an upward force recognized as the buoyant force on any entity submerged in them.
4. The unit of the buoyant force is $\mathrm{Newton}\left(\mathrm{N}\right)$.

Mathematical representation:

$\mathrm{Apparent}\mathrm{weight}=\mathrm{Weight}\mathrm{of}\mathrm{object}(\mathrm{in}\mathrm{the}\mathrm{air})–\mathrm{Thrust}\mathrm{force}\left(\mathrm{buoyancy}\right)$

Explanation:

1. Whenever the weight of a body equals the weight of the liquid displaced, the body floats in the fluid.
2. Any item submerged in a fluid, whether completely or partly, is buoyed up by a force equivalent to the weight of the fluid displaced by the object.
