Question

What happens to the buoyant force as more and more volume of a solid object is immersed in a liquid? When does the buoyant force become maximum?

Answer 1

Hint: Let's start with a definition of buoyant force before moving on to the equation. The pressure of the fluid determines the buoyant force. The fluid pushes an immersed object on all sides, but as pressure rises with depth, the push is stronger on the bottom surface than on the top.

Complete answer:
When an object is submerged in a liquid, buoyant force acts on it, causing it to rise. The sensation of being lifted aloft is known as buoyancy. As the volume of the solid object immersed in the liquid grows, the upward 'buoyant force' grows as well. The buoyant force acting on the solid reaches its maximum when the object is entirely immersed in the liquid and remains constant thereafter.

Additional Information: When the upward force on the bottom of an object is larger than the downward force on the top of the object when it is immersed in a fluid. Any object in any fluid will experience a net upward push (a buoyant force). The object will rise to the surface and float if the buoyant force is greater than its weight. The object will sink if the buoyant force is less than its weight. The object will remain hung at that depth if the buoyant force equals the object's weight. Whether an object floats, sinks, or remains suspended, the buoyant force is always present in a fluid.

Note: In swimming, buoyancy is crucial because it allows the swimmer to stay closer to the surface. This is due to the fact that the pressure felt by the swimmer beneath the water is greater than the pressure felt above. This is also why swimmers are able to float on the water's surface.
