Question

defination of aechemedes principal

Answer 1

Hope it helps...!!!!

-----------------------------------

✔️A law of fluid mechanics: a body while wholly or partly immersed in a fluid apparently loses weight by an amount equal to that of the fluid displaced.

OR

✔️When an object is dropped in a water tank, the water level is increased. This brings out the result in the displacement of the volume of water which is equal to the volume of an object. The object will make a space in the water tank by forcing out water causing the water level rise. According to Newton's third law statement in Archimedes principle it states that if an object is impacted on the water, the opposite force from the water will be exerted on an object which is known as buoyant force.

Archimedes principle buoyancy is illustrated in FIGURE (Check this attachment). ☺️

Answer 2

Archemides's principal states that the buoyant force that is exerted on the body immersed in a fluid , whether fully or partially submerged ,is equal to the weight of a fluid that the body displaces and act in the upward direction at the centre of the mass displaced fluid.
