Question

What is the principal cause of buoyant force on a body submerge partially in fluid?

Answer 1

Explanation: The principal cause of action of buoyant force on a body submerged partially or fully in fluid is the force equal in magnitude to the weight of the volume of displaced fluid. ... Explanation: By changing the shape of an object it can be made to float on a fluid even if it is denser than that fluid.

Answer 2

$\huge \boxed{\bold \pink {Answer}}$

pressure exerted by a liquid increase with depth and act in all direction. So, the upward force exerted by the liquid on the bottom of an object is greater than the downward force acting on the top of the object. This gives rise to net force acting on the object in the upward direction, which accounts for the buoyant force.
