Question

explain the law of floatation and related assumptions

Answer 1

Answer:

An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. ... When any boat displaces a weight of water equal to its own weight, it floats.

Answer 2

Explanation:

Laws of Floatation:

A body floats in a liquid if:

1. Density of the material of the body is less than or equal to the density of the liquid.

2. If density of material of body is equal to density of liquid, the body floats fully submerged in liquid in neutral equilibrium.

3. When body floats in neutral equilibrium, the weight of the body is equal to the weight of displaced liquid.

4. The centre of gravity of the body and centre of gravity of the displaced liquid should be in one vertical line.
