An object immersed in water will be buoyed upward by a force equal to what?

• A. Half the weight of the object
• B. Equal to the weight of the object
• C. Twice the weight of the displaced water
• D. Equal to the weight of the water it displaces

Answer: (D)

An object immersed in water experiences an upward buoyant force due to the water it displaces. This buoyant force is described by Archimedes' Principle, which states that the upward buoyant force acting on a submerged object is equal to the weight of the fluid that the object displaces. Therefore, the correct answer indicates that the upward force is equal to the weight of the water it displaces. This principle is key in understanding why some objects float while others sink. An object will float if its density is less than that of the water because it will displace enough water to generate a buoyant force equal to its own weight. Conversely, if an object's weight is greater than the weight of the water it displaces, it will sink. Understanding this concept is essential for divers, as it directly relates to buoyancy control and safety during diving activities.
