Question

Buoyant force acting on a body due to different fluids is

• A. same
• B. different
• C. zero
• D. none of these

Answer 1

The correct option is B

different

Explanation

1. The buoyant force is the net upward force on any object in any fluid.

$F_b=V_s\times D\times g$

Where $F_b$is buoyant force, $V_s$ is the volume of a submerged object, D is the density, and g is the acceleration due to gravity.

2. If the buoyant force is greater than the object's weight, the object will rise to the surface and float.

3. If the buoyant force is less than the object's weight, the object will sink.

4. The buoyant force is directly proportional to the density of the fluid.

5. As we know, different fluids have different densities. Therefore the buoyant force acting on a body due to different fluids is different.

Hence, the correct option is (B).
