Answer:

Archimedes' principle describes the relationship between the buoyant force and the volume of the displaced fluid, but also the density of the displaced fluid.

Explanation:

Well,

His principle in equation form as:

FB = ρf Vf g

where FB is the buoyant force, ρf is the density of the displaced fluid, Vf is the volume of the displaced fluid, and g is the acceleration due to gravity, 9.8 m/s2. It's very important to remember that the density and volume in this equation refer to the displaced fluid,

not the object submerged in it.

For example, say you submerge an object in water and find that the object displaces 1.0 liter of water. Water has a density of 1.0 kg/L, so now we have everything we need to determine the buoyant force acting on the submerged object because we have the volume and density of the displaced fluid. Consequently, we also have the volume of the object because this is the same volume as that of the displaced fluid!

To calculate the buoyant force, simply put in number . Now our equation reads: FB = 1.0 kg/L * 1.0 L * 9.8 m/s2.

Once we calculate, we find that the buoyant force equals 9.8 kg-m/s2, which is the same as 9.8 Newtons.

If the weight of the object more than

9.8 N, the object will sink. If it is less than 9.8 N then, it will float.

But if the weight of the object same as 9.8 N, Then It will neither sink nor float

bcose it is the same as buoyant force.

Answer:

Archimedes' principle can be stated as follows:

Any body completely or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the body.

Everyone has experienced Archimedes' principle. As an example of a common experience, recall that it is relatively easy to lift someone if the person is in a swimming pool whereas lifting that same individual on dry land is much harder. Evidently, water provides partial support to any object placed in it. The upward force that the fluid exerts on an object submerged in it is called the buoyant force.

According to the Archimedes' principle,

The magnitude of the buoyant force always equals the weight of the fluid displaced by the object.

The buoyant force acts vertically upward through what was the center of gravity of the displaced fluid.

                  B = W

Where B is the buoyant force and W is the weight of the displaced fluid.

The units of the buoyant force and weight are newton ( N ) in SI and "pound force" ( lbf) in British Engineering units.

The buoyant force acting on the steel is the same as the buoyant force acting on a cube of fluid of the same dimensions. This result applies for a submerged object of any shape, size, or density.
