Sarala, this happens because of upward force called buoyancy and this is always equal to the weight of the water the object displaces. For example, if an object of 5 kg displaces an amount of water suppose of 2kg then the weight of the object in water equals to 5kg - 2 kg = 3kg.

 Here is the reason. Archimedes principle says when a body is partly or totally immersed in a fluid, there is an upthrust that is equal to the weight of the fluid displaced.

When body immersed force acts on upward and slowly it reduces and body comes out.
