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 have zero friction, regardless of compression. The plates also have zero friction. One plate, plate A, has a hole through it leading to a chamber with perfect vacuum and is rigidly supported. The other plate, plate B, is not secured to anything. Would plate B fall? Please support your answer with formulas, free body diagrams, etc. Initially I believed the plate would fall. However, I am wondering: 1. Does the mass of Plate B matter? 2. Is the force of a perfect vacuum greater than the force of gravity? Thanks for reading and sharing your knowledge!
