Question

(iv) State the law of flotation. How does the density of a body and that of a liquid determine whether the body
will float or sink into the liquid?

​

Answer 1

IT WILL FLOAT ON THE LIQUID  !

Answer 2

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

laws of flotation are -:

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.
