A conducting solid sphere of radius R1 = 30 cm with charge 4.0nC is at the center of a conducting hollow sphere of inner radius R2 = 70 cm and outer radius R3 = 80cm. The hollow sphere has charge -1.5 nC. The spheres are isolated. Take the origin as the center of the spheres. Take the potential at infinity as zero. A) Calculate the potential origin at the center.
B) Suppose that a conducting wire is used to connect the solid sphere to the inner surface of the hollow sphere, and electrostatic equilibrium is reached Calculate the electric potential at the origin
C) Suppose that the hollow sphere is connected by a conducting wire to the ground, while the solid sphere is kept isolated Calculate the potential at the origin
