Interesting question about electrostatic induction

A conductive plate with no initial charge is put between two identical positevily charged plates. Is it possible that the plate which is put between those two plates configures a situation where the net force acting upon each plate is zero? (the third plate could have different dimensions then the two positevily charged plates)

As far as I can figure, the E field between those two plates is zero so no charge in the third plate can be induced and the putting of the third plate wouldnt change anything.

I think the positively charged plates would pull the electrons on the middle plate toward the surface of the plate. The (very rough) schematic would look something like this:

But the plate is uncharged. Where would the electrons come from.
There can be no charge inside the conductor.
Nothing would happen.

Right. Gotcha. Forgot about that whole no charge in the conductor thing.
