Question

Do all body is immersed in a given fuel expression the same buoyant force explain

Answer 1

no, depends upon the wieght of the body

Answer 2

Hi there
Here's your answer

No, they don't. The “buoyancy force” is nothing but the resistive force applied in upward direction to counter the weight of the body. It is the static pressure on the immersed surface of the body, integrated over the immersed surface area. The static pressure in a fluid increases with depth from it's “free” surface and it is directly proportional to the fluid density (denser fluids offer more buoyancy at same depth than lighter fluids, e.g. A tennis ball can suspend in water, but not in air.). By simple law of Force equilibrium, if weight of body is more than buoyancy force (downward force is more than upward force) the body sinks, if it balances the weight, the body floats.
