Question

Enlist 4 factors on which buoyant force due to a liquid on a body depends.

Answer 1

1-Volume of the body submerged in the liquid or volume of the liquid displaced
2-Density of the liquid
3-Acceleration due to gravity

Volume

When we push a small piece of cork into water, we experience some up thrust on our fingers. Suppose if we push a bigger piece of cork into water, we experience a greater up thrust on our fingers. Thus, it can be said that the buoyancy force increases with increase in the volume of the object.

Density

When we push a small piece of cork into water, we experience some up thrust on our fingers. Let us add some salt to the water and repeat the same experiment. It can be observed that we experience more up thrust on our fingers. With this it can be concluded that buoyancy increases with increase in density.

Acceleration due to gravity

The force of buoyancy also increases with increase in acceleration due to gravity.
