Question

Does the buoyant force act in liquid only or in all the states?

Answer 1

• The buoyant force is the upward force exerted on an object wholly or partly immersed in a fluid.
• The upward force exerted is also called upthrust.
• The buoyant force is directly proportional to the density of the fluid.
• Objects of equal volumes, regardless of their masses, feel equal buoyant forces when submerged in the same type of fluid.
• If an object is submerged, it displaces its total volume of fluid. The buoyant force on each object is the same because of identical pressure environments and equal water displacement.
