Question

do all body is immersed in a liquid fluid experience the same buoyant force explain

Answer 1

depends o the mass of the body ............this is it and in short

Answer 2

Buoyancy means a force that cause to object float. According to the principle of Archimedes when a solid is float in liquid or gases, it is subject to an upward force equal in magnitude to the weight of the fluid it has displaced.
Thus different bodies can displace different weight of fluid and thus they experience different buoyant force
