Definition
Whenever an object is partially of wholly immersed in a liquid then the liquid obviously apply some force on the object pushing it upwards that's what we call upthrust.
Remember ,
Upthrust = Weight of Fluid Displaced
This is explain by Archimedes principle.
More the force applied by the object more will be the water displaced.
So that's all about action and reaction phenomena.
Causes :
The main cause of thrust is the upward force exerted by the liquid.
So one main find the heavier objects floating upwards in the water it is due to the buoyancy that acts on the all direction.
As you increase the depth of thrust would also be increased.
Formula :
VDg
V = Volume of the liquid
D = Density
g = acceleration due to gravity.
