state and explain Archimede's principle?A body of mass 2Kg and density 8000Kg/m2 is completely dipped in a liquid of density 800Kg/m3.Find the buoyancy on it?
Answers
Answer:
Archimedes principle states that:-
The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
Explanation:-
The value of thrust force is given by the Archimedes law which was discovered by Archimedes of Syracuse of Greece. When an object is partially or fully immersed in a liquid, the apparent loss of weight is equal to the weight of liquid displaced by it.
Explanation:
☛Buoyant force = Upthrust = mass of liquid displaced.
So,
☛ Mass of liquid displaced = Volume of liquid displaced × density of the liquid
By Archimedes principle, we know that when an object is partially or completely immersed in a liquid then the volume of liquid displaced is equal to the volume of immersed part of the object.
So,
☛ Volume of liquid displaced = Volume of the body
➡️Mass of body = 2kg
and it's density = 8000kg/m³
Thus, mass of water displaced
= volume of liquid displaced × density of liquid
Therefore, the upthrust or buoyant force
➡️ Therefore, the force is 1.96 N
