Question

A body of mass 2.0 kg and density 8,000 kg/m3 is completely immersed in a liquid of density 800 kg/m3. Find the force of buoyancy on it.

Answer 1

Here is your answer

Volume of body immersed =2/8000

=0.00025m3

Density=800kg/m3

Buyant force ,F(b)=VDG

=0.00025×800×10=2N

Answer 2

The force of buoyancy, also known as the buoyant force, is an upward force exerted on an object that is submerged in a fluid. The buoyant force is equal to the weight of the fluid that is displaced by the object.

          Buoyancy = 0.196N

In this case, a body of mass 2.0 kg and density 8,000 kg/m3 is completely immersed in a liquid of density 800 kg/m3. To calculate the buoyant force, we use the formula:

Buoyant Force = fluid density * volume of fluid displaced * acceleration due to gravity

The volume of fluid displaced is equal to the volume of the body, which we can calculate using the formula:

Volume = mass/density

Using the given values, we can calculate the volume as:

Volume = 2.0 kg / 8,000 kg/m3 = 0.00025 m3

Next, we can calculate the buoyant force as:

Buoyant Force = 800 kg/m3 * 0.00025 m3 * 9.8 m/s2

= 0.196 N

So, the force of buoyancy on the body is 0.196 N. It is important to note that the buoyant force will always act upward and be equal in magnitude to the weight of the fluid that is displaced, but opposite in direction.
