as you know that inside a capacitor electric field remains same. If you increase the distance between the two plates electric field does not change just because electric field= surface charge density/ epsilon. so E=V/D gives increment in V as D increses so that electric field remain same. ... A capacitor has an even electric field between the ...
The standard examples for which Gauss'' law is often applied are spherical conductors, parallel-plate capacitors, and coaxial cylinders, although there are many other neat and interesting charges configurations as well. To compute the capacitance, first use Gauss'' law to compute the electric field as a function of charge and position.

$begingroup$ Alfred Centauri, yes I did and since the points outside the external sphere are closer to the the external sphere than the inside sphere, the "negative electric fiel" (electric field of the external sphere) is stronger than the "positive field" in the points outside the sphere. So the fields have the opposite directions and at first they could cancel each other but …

A spherical capacitor is a type of capacitor formed by two concentric spherical conducting shells, separated by an insulating material. This configuration allows it to store electrical energy in the electric field created between the two shells, and its geometry makes it particularly useful in various applications requiring uniform electric fields and high capacitance values.
The capacitance of a conducting sphere is directly proportional to the radius of the sphere. The bigger the sphere, the more charge you have to put on it to raise its potential …

Figure (PageIndex{2}): Electric field lines in this parallel plate capacitor, as always, start on positive charges and end on negative charges. Since the electric field strength is proportional to the density of field lines, it is also proportional to the amount of charge on the capacitor.

The more interesting case is when a spherical charge distribution occupies a volume, and asking what the electric field inside the charge distribution thus becomes relevant. In this case, the charge enclosed depends on the distance r of the field point relative to the radius of the charge distribution R, such as that shown in Figure 6.23 .
The outer surface of the inner sphere and the inner surface of the shell form a spherical capacitor whose field can be easily calculate. ... without sphere 1 inside. By Gauss''s law you know that the static field of a charged surface enclosing an empty volume is zero inside that volume. The end result is that only sphere 1 determines the field.

A spherical capacitor is a type of capacitor that consists of two concentric spherical conductive shells, which are separated by an insulating material called a dielectric. This arrangement allows for the storage of electrical energy due to the electric field created between the two spheres when a voltage is applied. The spherical design leads to unique capacitance properties, making it …

Figure 5(b) shows the electric field lines with a dielectric in place. Since the field lines end on charges in the dielectric, there are fewer of them going from one side of the capacitor to the other. So the electric field strength is less than if there were a vacuum between the plates, even though the same charge is on the plates.
