Why does an object lose its weight when immersed in a liquid?

Open in App

Solution

When an object is immersed in a liquid, it is acted upon by two forces:
Weight of the object, acting vertically downwards.
Buoyant force due to the liquid, acting vertically upwards.
Hence when an object is immersed in a liquid, there is a loss in the weight of the object. This loss in weight is known as apparent loss in weight.
