  • A point charge q=-5.010-112c is placed at the center of a spherical conducting shell of inner radius 3.5cm and outer radius 4.0cm. The electric field just above the surface of the conductor is directed radially outward and has magnitude 8.0N/c.
  • (a) What is the charge density on the inner surface of the shell?
  • (b) What is the charge density on the outer surface of the shell?
  • (c) What is the net charge on the conductor?
