Nugatory, thank-you for your detailed explanation! The component I was missing was the zero net sideways force due to the seals. I also fell into the trap of misunderstanding vacuum. Now I'll be able to sleep.

I'm guessing most people would think the plate would fall, but I could be wrong. So I created another version of the problem. See attached image which I created (not copied from a textbook or exam) where the plates are now parallel to the ground. In this case, as long as the mass is of...

I believe the plate would fall. My argument was in a real world situation, the force preventing the red plate from falling would only be friction. Vacuum enables friction, but vacuum would not directly prevent the red plate from falling. However, coefficient of friction greater than the force...

I have a theoretical question for physicists. For reference, see attached image. Suppose you have two perfectly flat plates aligned laying adjacent to each other. The plates are parallel to gravity. (perpendicular to the ground). Between the plates are perfect seals (no leaking). The seals...
