The lead ball and the soap bubble have equal volumes. Are the magnitude of the Archimedean forces acting on these balls in the air equal?
The essence of Archimedes’ law: a body immersed in a liquid (located in a gas) is subjected to a buoyant force equal in modulus to the weight of the displaced liquid (gas). The bubble and the lead ball displace the same amount of air because they have the same volume. This means that the weight of the displaced air will be the same. In turn, the weight of the displaced air is equal in magnitude to the Archimedes force, which acts on the soap bubble and the lead ball. Thus, this force is the same for these bodies.
