A point charge of 6.0 nC is placed at the center of a hollow spherical conductor (inner radius = 1.0 cm, outer radius = 2.0 cm) which has a net charge of -4.0 nC. Determine the resulting charge density on the inner surface of the conducting sphere.
 a. +4.8 mC/m2
  b. -4.8 mC/m2
  c. -9.5 mC/m2
  d. +9.5 mC/m2
  e. -8.0 mC/m2

Question 2

The electric field just outside the surface of a hollow conducting sphere of radius 20 cm has a magnitude of 500 N/C and is directed outward. An unknown charge Q is introduced into the center of the sphere and it is noted that the electric field is still directed outward but has decreased to 100 N/C. What is the magnitude of the charge Q?
 a. 1.5 nC
  b. 1.8 nC
  c. 1.3 nC
  d. 1.1 nC
  e. 2.7 nC
