Can you help me with this hard question please? 2. A spherical capacitor consists of an inner solid conducting sphere of radius a surroundedby a spherical conducting shell of inner radius b and outerradius e. The capacitor is charged with -Q on the inner sphereand +Q on the outer spherical shell.a) Derive expressions for the electric field everywhere in spacedue to this charge configuration, indicating both direction andmagnitude, in terms of the distance r from the center. Graphthe electric field magnitude as a function of r.Q-Qb) What is the surface charge density on the outer surface of theinner sphere and on the inner surface of the outer sphere?c) In part d) you will calculate the potential difference AV between the inner and outerconductors. Before you calculate the value, indicate what the sign (positive or negative)of AV=Vb – Va must be and give a clear explanation as to why.d) Determine the potential difference AV=Vb – Va between the inner and outer conductors.e) From the result in d), determine the capacitance of this device and the energy stored in it.
