Why changing the distance between two parallel plates capacitor …

Now there is only an excess of 3 red marbles on one side of the table and 3 black marbles on the other side of the table. The increase in distance across the table is analogous to the increase in plate separation. It requires more work per unit charge to move charge from one plate to the other.

8.5: Capacitor with a Dielectric

Once the battery becomes disconnected, there is no path for a charge to flow to the battery from the capacitor plates. Hence, the insertion of the dielectric has no effect on the charge on the plate, which remains at a value of (Q_0). ...

Dielectrics in capacitors

Capacitors use non-conducting materials, or dielectrics, to store charge and increase capacitance. Dielectrics, when placed between charged capacitor plates, become polarized, reducing the voltage across the plates and increasing capacitance. The degree of capacitance increase depends on the dielectric constant of the material used. By David Santo Pietro.

Another useful and slightly more intuitive way to think of this is as follows: inserting a slab of dielectric material into the existing gap between two capacitor plates tricks the plates into thinking that they are closer to one another by a factor equal to the relative dielectric constant of the slab. As pointed out above, this increases the capacity of the capacitor to store …

What is the electric field in a parallel plate capacitor?

When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $${bf E}=frac{sigma}{2epsilon_0}hat{n.}$$ The factor of two in the denominator comes from the fact that there is a surface charge density on both sides of the (very thin) plates.
