When the capacitor will cause the electric field around the charge. By the intensity of the electric field at any position is inversely proportional to the distance squared of the electric charge.
When there are free charge produces an electric charge around the intensity of electric at any position is variable, the inverse squared distance from the electrical charge.
When you are completely free to make independent, electric charge around the electricity intensity of the field at any location will be inversely proportional to alter the distance is two from ion.
