Hello.
I have a question or two about buoyancy, in water specifically. What causes buoyancy, if there is something more than the difference of pressures above and beneath an object?
What would happen if I put a very thin object in water, so that the difference in pressures would be extremely small?
And what would happen if I put an object (cone, for example) at the very bottom of a water filled glass, would it come back up (supposing it wouldn't sink if I just put it in the glass), and why? Which forces would affect the object?
English is not my native language, so I can't express myself the way I want to, but oh well.
