What is upthrust or buoyant force? what are the basic three properties of upthrust?
Answers
Explanation:
the upward force that a liquid or gas exerts on a body floating in it.
the basic 3 things are
The unit of upthrust is Newton. its formula is = VDg where V is the volume immersed D is the density of liquid and g is the acceleration due to gravity.
❣️ UPTHRUST ❣️
The upward force exerted on a body by a fluid in which that body is submerged,is called as upthrust or buoyant force.
When a body is partially or wholly immersed in a liquid,an upward force called upthrust or buoyant force acts upon it.
❣️ BUOYANCY ❣️
The property of a fluid (basically liquid) to exert an upward force on a body immersed in it, is called buoyancy.
❣️ THREE PROPERTIES ❣️
1) Larger the volume of body submerged in a fluid, greater is the upthrust.
2) For same volume inside the fluid, more the density of fluid, greater is the upthrust.
3) The upthrust acts on the body in upward direction at the centre of buoyancy.
