Question

State two factors on which buoyant force acting on a solid immersed in a liquid depend?

Answer 1

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.
