Question

Prove that the loss in weight of a body when immersed wholly or partially in a liquid is equal to the buoyant force and this exists because of difference in thepressures of the liquid exerted on the upper & lower surfaces of the submerged part of the body

Answer 1

when a body is submerged in water the water which comes out is equal to the mass of the body.
and also when a body is immersed in water if the buoyancy force is equal so that it will keep floating on water. and also atmospheric pressure also keep on the body so the buoyancy force is equal
