Final answer:
The buoyant force acts on all objects in fluid, as dictated by Archimedes' Principle. The object will experience a net upward force, which can lead to it floating, sinking, or remaining suspended in the fluid.
Step-by-step explanation:
Does Buoyancy Force Act on All Objects in Fluid?
It is true that the buoyant force acts on all objects that go into a fluid. According to Archimedes' Principle, the buoyant force is the net upward force on any object in a fluid. This occurs because pressure in a fluid increases with depth, which creates a greater pressure on the bottom of the object than on the top, leading to a net upward force. Whether an object floats, sinks, or remains suspended, the fluid exerts a buoyant force on it based on the amount of fluid it displaces.
If the buoyant force is greater than the object’s weight, the object will float. If the buoyant force is less, the object will sink. In the special case where the buoyant force equals the object’s weight, the object will remain suspended at its current depth in the fluid.
