I may be completely out of whack here but this kept me up last night...
Suppose a cork from a wine bottle is taken down to a depth of X metres. Since cork is less dense than water it will obviously float to the surface. I was thinking about manipulating the formulae.
Buoyancy force = Vρg
Pressure = Force/Area [itex]\Rightarrow[/itex] Force = ρghA
Is there a point in the liquid where ρghA = Vρg and the cork remains stationary.
hA = V
My physics teacher said I am completely off track (I'm beginning to agree with her because it's extremely non intuitive) but never gave me a real reason as to why...
Any help appreciated, thanks.
