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...
There are two charges with charge q and mass m and they are in equilibrium. Then, in the diagram why is my teacher saying that electrostatic force(F)=mg? Below is diagram.
