Question

List the buoyant forces on the three spheres from highest to lowest. If the buoyant forces are the same, indicate that they are the same.

(a) Same, Same, Same
(b) Highest, Same, Lowest
(c) Highest, Lowest, Same
(d) Same, Lowest, Highest

Answer 1

The buoyant force on three spheres submerged in the same fluid is the same assuming they have equal volumes because of Archimedes' Principle that equates buoyant force to the weight of the displaced fluid.The correct answer to the question, given the principles mentioned, would thus be (a) Same, Same, Same.

Step-by-step explanation:

The question relates to the application of Archimedes' Principle, which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid that the object displaces. This means that if three spheres are submerged in the same fluid and have the same volume, they will displace the same amount of fluid and therefore experience the same buoyant force irrespective of their mass or material composition. Consequently, without additional information suggesting that the spheres are of different sizes or submerged in different fluids, it is reasonable to conclude that the buoyant forces on all three spheres would be the same, as they would all displace the same volume of fluid.
