a) By using Gauss’s law, find the electric field inside, outside and inbetween two concentric spherical metal shells, assuming that the inner shell, of radius a, carries a charge of -Q and the outer shell, of radius b, carries a charge of Q.

b) By making use of the result in part (a), find the energy stored in the system made of two concentric spherical metal shells.

c) By using the result in part (a) find the electric potential difference between the two concentric spherical metal shells, with radii a and b.

Consider two concentric spherical shells with different radii, namely one is inside the other. The spherical shell inside has radius R1 = 7.00 cm and charge q1 = +3.00×10^-6 C; the spherical shell outside has radius R2 = 17.0 cm and charge q2 = −5.00×10^-6 C. For both shells charges are distributed uniformly over their surfaces. Assume that V = 0 at large distances from both shells. A) Find the electric potential of the two shells at the distance r...
