Question
State and explain Archimedes’ principle. What is buoyancy? Mention the factors on which buoyancy depends.
Answer
Archimedes’ principle states that an object immersed in a fluid experiences an upward buoyant force that is equal to the weight of the fluid displaced by the object. This principle can be explained by the fact that the pressure at the bottom of the object is greater than the pressure at the top, resulting in a net upward force.
Buoyancy is the upward force exerted by a fluid on an object that is partially or completely immersed in it.
Buoyancy depends on the following factors:
- The density of the fluid in which the object is immersed.
- The volume of the object that is submerged in the fluid.
