The charge is influenced like in situation 1. But since the wall is a dielectric it depends on the polarisation which value the influenced charge density has.

But in your example both plates are charged with ##\vert \sigma>0\vert##. In my example the lower plate has a charge density ##-\sigma>0## an the upper plate has ##\sigma_0 = 0##. So the situation is asymmetric per se.

But what about the fact that the electric field of the charged plate is uniform? The force attached to every point is equal in direction and magnitude. So the resulting force should be zero? I'm not sure how to use this if we have a charged and an uncharged plate. Can you give more details?

Hi, I'm dealing with a more or less trivial question. Let's have a look on two situations. Consider a (negative) charged metal plate. If the plate is infinit in size it will produce a perfekt homogeneous electric field. If we now place a second plate parallel to the first one the electric...
