According to Archimedes' principle, the buoyant force on a submerged body equals the:
Correct answer: A. Weight of the displaced fluid
- A. Weight of the displaced fluid
- B. Weight of the submerged body
- C. Mass of the displaced fluid
- D. Pressure at the lower surface
Explanation
Buoyant force equals the weight of the fluid displaced by the body. The body's own weight determines whether it rises, remains suspended or sinks, but it is not the buoyant force itself.

About Hydraulics and Water Resources
Hydraulics studies fluid properties, pressure, buoyancy, continuity, Bernoulli's equation, momentum, pipe flow, open-channel flow and hydraulic machines. Water resources extends these principles to pumps, turbines, reservoirs, irrigation, floods and hydrology, while distinguishing laminar from turbulent flow and uniform from gradually varied channel flow.
