Question

An object weight 10 N in air. When immersed fully in water, it weights only 8 N. what will be the weight of liquid displaced by the object.

Plzzzzz give me a proper answer.... ​

Answer 1

The weight of liquid displaced is 2 N.
Reason : In the air the force acting is on mg.
but when immersed in water buoyant force acts on it in upward direction which is exerted by the volume of liquid displaced.S o from this we can get weight of liquid displaced.

Answer 2

The weight of the object : 10 N

When it is immersed fully in water, buoyant force of water acts on the body, resulting in displacement of water from the container.

The Archimedes Principle states that :

When an object is immersed fully or partially in a liquid, it experiences an upward force which is equal to the weight of the object displaced.

According to this principle,

The weight of the object in the water : 8N

So the weight of the liquid displaced will be 2N

(10N - 8N)

Which is because of the buoyant force acting on the object by the water.

Hope it is clear :-)
