Buoyant force or upthrust: The force tending to lift up the body when it is wholly or partially immersed in liquid (or any fluid) is called buoyant force or upthrust. It is determined by Archimedes’ principle which states that,“ when a body is wholly or partially immersed in a liquid (or any fluid), it is lifted up by a force which is equal to the weight of the fluid displaced by the body”. Buoyant force or Upthrust = weight of fluid displaced by body   Centre of buoyancy : The point of application of force of buoyancy on a body is known as the center of buoyancy.  It is located at the center of mass of the displaced liquid. Types of fluid :   i.               ...
