Question

Archimedes principle states

Buoyant force acting on a body is equal to two times the weight of the fluid displaced by the body.

None of the above

Buoyant force acting on a body is equal to the weight of the body.

Buoyant force acting on a body is equal to weight of the fluid displaced by the body.

Solution

The correct option is **D**

Buoyant force acting on a body is equal to weight of the fluid displaced by the body.

According to Archimedes principle, the buoyant force acting on a body which is partially or fully immersed in a fluid, is equal to weight of the fluid displaced by the body.

Buoynat force, FB=ρVdispg

where Vdisp = Volume of fluid displaced by the body

ρ = Density of the fluid

g = Accelaration due to gravity
