Two concentric spheres are shown in the figure. The inner sphere is a solid nonconductor and carries a charge of -5.00 µC uniformly distributed over its outer surface. The outer sphere is a conducting shell that carries a net charge of 8.00 µC. No other charges are present. The radii shown in the figure have the values R1 = 10.0 cm, R2 = 20.0 cm, and R3 = 30.0 cm.
(a) Find the total excess charge on the inner and outer surfaces of the conducting sphere.
(b) Find the magnitude and direction of the electric field at
the following distances r from the center of the inner sphere (i) r
= 27.0 cm (ii)35 cm.
