Question
Consider an electrostatic arrangement containing of two concentric spherical shells and a point charge Q placed in the common center. The spherical shells are perfect electrical conductors. The inner spherical shell is neutral (i.e., the total net charge is 0), it has a inner radius, a and a outer radius b. The outer shell has a charge –Q and has a inner radius c and a outer radius d; a < b < c < d.There is vacuum in the areas 0 < r < a, b < r < c and r < d, where r represents the distance to the common center.
a) Determine the size and direction of the electric field in each of the five areas:
0 < r < a, a < r < b, b < r < c, c < r < d and r > d.
b) Explain the presence of the Electric charge and how it is distributed. Define for r > 0 the corresponding charge density.
