    Pressure of captured air under water

    Thank you very much for this explanation and my apologies for the confusion, that I realize may have arisen by using the word "submerged" in my question. Yes! It's a very interesting result that comparing two buckets, one with A=1m2, L=1m and the other has A=1m2, L=2m, yet both with the same...

    Pressure of captured air under water

    Thank you for your patience. I am afraid I am still not completely grasping it. Am I understanding correctly that N equals the downwards force induced by the mass on the bucket (which was given as 1000N)? So if we set it to zero, h should also be zero because the bucket would float on the...

    Pressure of captured air under water

    Thank you very much. I think I understand your formula. Although I must say this is even more counterintuative. I would think that if I attach 100kg to the (idealized 0 mass) bucket placed on the water surface, also 100kg of water would be displaced, so the top of the bucket would sink only...

    Pressure of captured air under water

    For a construction I am building, I am stumbling on a rather basic physics question regarding pressure. Let's say I have a cubic bucket of 1m^3 that I place upside down on a water surface. I add a downward force (weight) of say 1000N submerging the bucket under water with the air captured...
