Why is the electric field inside the dielectric cancelling?

  1. Jun 21, 2017 #1
    So, I was studying force between the plates of a capacitor when a dielectric is inserted.

    Here is my question

    Shouldn't it be like this picture below

    So, why is my teacher saying that the electric field inside the dielectric cancelling.
    So, what would be the force on a plate then?

    The reason is that the plate polarises the diaelectric and that creates the oposite field inside the other plate which cancels with the first.

    But, they are in same direction
