I have attempted it myself. It was in a quiz in school! I want to know if my answer is right.
I stated that there was no change in the individual heights or the difference in heights since pressure= density*gravity*height and since pressure, density and gravity were constant, so was height. But I don't know whether saying that the individual water levels would not change was right.
I'm awfully sorry about that. Can I just check one thing: so you're saying that despite there being a certain amount of water, when the pressure diameter is increased, the water levels don't fluctuate at all?
I know their difference will remain at X. But will their individual water levels change.
