State whether the following statements are true or false:
(a) The buoyant force depends on the nature of object immersed in the liquid
(b) 'Archimedes' principle can also be applied to gases.
Solution: (a) The buoyant force depends on the nature of the object immersed in the liquid - False. Since buoyancy depends only on the volume of the object and the density of the fluid, thus it is not dependent on the nature of the object.
(b) YES. Archimedes' Principle is applicable to gases also. Gases and liquids are classified as fluids. ... Gases also exert buoyant force on objects but it is very small.
