Question

Archimedes' major contribution / discovery was:

• A. Photoelectric effect
• B. Principle of buoyancy
• C. Wave theory of light
• D. Law of inertia

Answer 1

The correct option is B Principle of buoyancy

Answer is B

Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Because of this buoyancy a body is able to float or submerge over liquid surface.
