Thus electric field outside of dielectric in lower part of capacitor is not equal to the electric field in upper part of capacitor. Thus in order to avoid long approach, you can consider your book statement.(which I assume you understand) Altenatively: To find the charge on each capacitor, you will use the fact the potential difference of 2 capacitors is same. You might want to do that
This box has six faces: a top, a bottom, left side, right side, front surface and back surface. Since the top surface is embedded within the metal plate, no field lines will pass through it since under electrostatic conditions there are no field lines within a conductor. Field lines will only run parallel to the area vector of the bottom

A spherical capacitor stores charge by creating an electric field between the inner and outer spheres when a voltage is applied across them. The inner sphere acquires a charge, while an equal but opposite charge accumulates on the inner surface of the outer sphere, creating a potential difference and storing energy.
The structure of a spherical capacitor consists of two main components: the inner sphere and the outer sphere, separated by a dielectric material Inner Sphere (Conductor): The inner sphere of a spherical capacitor is a metallic conductor characterized by its spherical shape, functioning as one of the capacitor’s electrodes.
Uniform Electric Field: In an ideal spherical capacitor, the electric field between the spheres is uniform, assuming the spheres are perfectly spherical and the charge distribution is uniform. However, in practical cases, deviations may occur due to imperfections in the spheres or non-uniform charge distribution.
The electric field between the two spheres is uniform and radial, pointing away from the center if the outer sphere is positively charged, or towards the center if the outer sphere is negatively charged. A spherical capacitor is a space station with two layers: an inner habitat where astronauts live and an outer shell protecting them from space.
Therefore, the potential difference across the spherical capacitor is (353 V). Problem 4:A spherical capacitor with inner radius ( r1 = 0.05 m ) and outer radius ( r2 = 0.1 m) is charged to a potential difference of ( V = 200 V) with the inner sphere earthed. Calculate the energy stored in the capacitor.
Capacitance: The capacitance of a spherical capacitor depends on factors such as the radius of the spheres and the separation between them. It is determined by the geometry of the system and can be calculated using mathematical equations.
Dielectric Medium: The space between the inner and outer spheres of a spherical capacitor is occupied by a dielectric material, serving a crucial role in the capacitor’s operation. This dielectric material functions to provide insulation between the two conductors while facilitating the formation of an electric field.
