What is the principal cause of action of buoyant force on a body subm...
Buoyant force is the upward force exerted by a fluid on a body that is partially or fully submerged in it. The principal cause of this force can be explained by the concept of displacement of fluid.
Displacement of Fluid:
When a body is partially or fully submerged in a fluid, it displaces some amount of fluid. The displaced fluid moves out of the way to accommodate the presence of the body. This displacement of fluid creates a void or empty space in the fluid where the body is located.
Archimedes' Principle:
According to Archimedes' principle, the buoyant force experienced by a body submerged in a fluid is equal to the weight of the fluid displaced by the body. This principle explains that the buoyant force is directly proportional to the volume of the displaced fluid.
Explanation:
The principal cause of action of buoyant force is the displacement of fluid due to the submerged body. When a body is submerged in a fluid, it displaces a certain volume of fluid equal to its own volume. This displacement creates a void in the fluid, which is then filled by the surrounding fluid.
The displaced fluid exerts an upward force on the body, which is the buoyant force. This force is exerted in the opposite direction to the force of gravity acting on the body. As a result, the body experiences an upward force that opposes its weight, making it feel lighter in the fluid.
The magnitude of the buoyant force depends on the volume of the displaced fluid and the density of the fluid. A denser fluid will exert a greater buoyant force compared to a less dense fluid, provided the volume of the displaced fluid remains the same.
In conclusion, the principal cause of action of buoyant force on a body submerged partially or fully in a fluid is the displacement of fluid due to the presence of the body. This displacement creates a void or empty space in the fluid, which is then filled by the surrounding fluid, exerting an upward force on the body known as the buoyant force.
