Question

A body of mass 2.0 kg floats in a liquid. What is the buoyant force on the body?​

Answer 1

Answer:

When a body is floating in a liquid then the weight of the body is equal to the buoyant force on the body Buoyant force =Weight of the body mg= 2×9.8=19.6 N. This discussion on A body of mass 2kg floats in a liquid.

Answer 2

Answer:

Thus, the buoyant force on the body is 19.6N

Explanation:

As per the question,

Given:

A body of mass 2.0 kg floats in a liquid.

To Find:

What is the buoyant force on the body.

Solution:

The force that makes a thing float is called buoyancy. Therefore, the force acting on an object that is partially or entirely submerged in a fluid is known as buoyancy.

Given data:

Mass of a body, m=2 kg

Buoyant force= ?

We know that density=$\frac{mass}{volume}$

volume= $\frac{mass}{density} =\frac{2}{1000} =0.002m^{3}$

We know that the buoyant force is given by, $f_{b } =Vdg$

Substituting the values, we get,

$f_{b} =0.002\times 1000\times 9.8 = 19.6 N$

Thus, the buoyant force on the body is 19.6N
