Question

define buoyancy state the two factors on which buoyant force depends

Answer 1

buoyancy is defined as the ability of an object to float in a fluid.

buoyancy depends on volume of immersed object, density of a liquid and acceleration due to gravity

Answer 2

hi friends.......

BUOYANCY is the ability or tendency of an object to float in a fluid, which can be a liquid or a gas. This happens because fluid pressure increases with depth. ... The upwards force that an underwater object feels is called the buoyant force

Buoyancy of a body depends on the following factors:

(1) Density of the liquid.

(2) Acceleration due to gravity.

Explanations.....

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.
