Dear student

When a solid particle is fairly or totally immersed in fluid, there is a defeat in the weight of particle in floatation. The loss in the weight of body is due to the up thrust acting on it.  Thus a particle flooded in a fluid is below the action of two factors in law of flotation such as,

W - weight for downward action of a body and
upward action of the body based in upthrust.
The floating and the shrinking of a body in a liquid depend on the relative magnitudes of some factors in law of floatation.


Hope this helps.
