When an object in water is lifted, what happens? What can be the reason?

Answer»

When an object in water is lifted, its weight appears diminished, when compared to that in air.

It is because water exerts an upward force on a body placed in it.

Fluids: Liquids and gases together are generally called fluids.

Buoyancy: When a body is immersed completely or partially in a liquid, the liquid exerts an upward force on the body. This force is the buoyancy.
