Polarized Molecule Between Charged plates

[Biodelta]

If a polarised molecule, e.g NH3 or H20 (Vapour molecule) or Butane is between two plates, of opposite charge,
would the charges serve to trap the molecule between the plates?

Thread difficulty level changed from "A" (graduate school) to "I" (undergraduate).

What do you think will happen? The field strength between charged plates is uniform / flat, at least away from the very edges of the plate. What does a uniform E-field do to a polar molecule?

Yes, this is precisely the question I have asked.
