why do the upthrust increase with increase in depth ?

Expert Answer:

Hi dear,

The Archimedes principle states that the up thrust force on an object wholly or partially immersed in a fluid is equal and opposite to the weight of the fluid displaced by the object. The following figure shows how the increase in pressure with depth affects an object immersed in a fluid. The pressure on the walls of the object will balance each other, but there will always be greater pressure below the object than above it. This pressure difference is the cause of the up thrust force.

The vertical forces acting on an object are at equilibrium for the object to float.

Hope this helped.
