# An object weighs $10\ N$ in air. When immersed fully in water, it weighs only $8\ N$. The weight of the liquid displaced by the object will be$(a).\ 2\ N$$(b).\ 8 N$$(c).\ 10\ N$$(d).\ 12\ N$

Here, the weight of the object in the air $=10\ N$

Weight of the object, when immersed in water $=8\ N$

According to Archimedes\' principle, the buoyant force$=$weight of the displaced liquid by the body.

Therefore, the weight of the liquid displaced by the object $=10\ N-8\ N=2\ N$

So, option $(a)$ is correct.
