Question

give the necessary condition for floating of sinking of an object in water​

Answer 1

Condition for Flotation

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 . ... When the buoyant force equals one ton, it will sink no further. When any boat displaces a weight of water equal to its own weight, it floats.

Answer 2

Explanation:

an object has a density less than the density of water, it floats. Like, leaf of a plant floats on the water because the density of leaf is less than the density of water. A stone thrown in water sinks because the density of stone is more than the density of water
