Hi I want to make sure my intuition is correct about the buoyant force.
What I am confused by if we take a cube or some sort of object and its submerged at height H1 as in picture I uploaded,then their will be a force of P1 * A; in case of the cube it's it would be d^2. What I don't understand or I am not sure that my intuition is correct is this is why the height of H2(height 2 not Hydrogen gas :D) is taken from the top of the water to bottom of the cube instead of bottom of the water to the bottom of the cube as picture 2 represent.
My intuition to this is as follows since the upward pressure P2 is same throughout the liquid then P2 if taken from frame of reference from above of the beaker it would be the same that if taken from frame of reference from bottom of the beaker as picture 2 represent.Is that intuition is correct ?
Please look at picture as they explain better than I do.
Thanks in advance.
