Question

Define bouyant force. State two factor in which it depends

Answer 1

if any thing is floating in water it will apply a Force on water but water apply upthrust on the thing it is known as buoyant force

it depends on volume of things and their density

Answer 2

The upward force exerted by a liquid on a body which is immersed in the liquid is known as the upthrust or buoyant force.

Factors on which buoyant force or upthrust depends:

Buoyant force is directly proportional to
1- the volume (V) of the object or body immersed in liquid.
2- the density ( ro)of the liquid in which the object or body is immersed.
3- the acceleration due to gravity (g) at the given place.

Hope this helps!!!!
