Two same cones are immersed in the water.
The buoyancy is equal to the difference of pressure suffered by the upper and nether surface of the object immersed in the water.
The buoyancy ia also equal to the weight of the fluid displaced by the object.
I have a queston now:
If a cone inverted immersed and a cone are normally immersed in the water,the difference of pressure are no same,so the buoyancy of them are also no same.
But they displaced the same weight of water,so their buoyancy are same.
How to explain this?
