Buoyancy

Buoyancy

It is said that the apparent weight loss = Weight of object - Upthrust

Also, it is said that the apparent weight loss is constant once the whole of the object's volume is submerged.

If both holds, then the Upthrust must be a constant once the object is fully submerged in the liquid. But upthrust changes with depth. Please explain how. 

Thanks

Once the object is fully submerged in liquid the buoyant force does not change with depth. It remains constant. This is because the volume displaced is fixed.
