respected sir i request you to please explain me this characteristic property of buoyancy:-[given my school module]

  • the upthrust acts on the body in upward direction at the centre of buoyancy i.e. the centre of gravity of the displaced liquid

Expert Answer:

The property of liquid to exert an upward force on an object immersed in the liquid is called buoyancy. 
When a body is immersed partially or wholly in a liquid, the upward force acts on this object. And this force is known a upthrust or buoyant force. 
For example - When we try to push an empty bottle into the water, we feel an upward force which resists the push and thus making it difficult to push the bottle further into the water. This upward force is nothing but a buoyant force.
