When an object is completely or partially immersed in a liquid, the apparent reduction in its weight is equal to the weight of the fluid displaced by that object. This principle is known as Archimedes’ principle [option B]. It states that the buoyant force exerted on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. This principle, formulated by the ancient Greek mathematician and scientist Archimedes, is fundamental in understanding buoyancy and the behavior of objects in fluids. It explains why objects float or sink in a fluid and provides insights into designing ships, submarines, and other vessels to achieve proper buoyancy and stability. Archimedes’ principle is widely applied in various fields, including naval architecture, engineering, and fluid mechanics, where the interaction between objects and fluids is crucial.
