Question
What is buoyancy? Show how and on what factor its value depends.
Answer
Buoyancy is the upward force exerted by a fluid on a body immersed in it. The value of buoyancy depends on the volume of the displaced fluid, the density of the fluid, and the gravitational force acting on the fluid and the body. Archimedes’ principle states that the buoyant force is equal to the weight of the displaced fluid.
