Who discovered a principle that states that the buoyant force on an object is equal to the weight of the fluid displaced by the object?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Archimedes.
The principle that states the buoyant force on an object is equal to the weight of the fluid displaced by the object was discovered by Archimedes. This is known as Archimedes' Principle, formulated in ancient Greece. According to this principle, when an object is immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This principle is fundamental in understanding flotation and buoyancy in liquids and gases.
