A long cylindrical conductor (radius = 1.0 mm) carries a charge density of 4.0 pC/m and is inside a coaxial, hollow, cylindrical conductor (inner radius = 3.0 mm, outer radius = 4.0 mm) that has a total charge of -8.0 pC/m. What is the magnitude of the electric field 2.0 mm from the axis of these conductors?
 a. 24 N/C
  b. 18 N/C
  c. zero
  d. 36 N/C
  e. 226 N/C

Question 2

A spherical conductor (radius = 1.0 cm) with a charge of 2.0 pC is within a concentric hollow spherical conductor (inner radius = 3.0 cm, outer radius = 4.0 cm) which has a total charge of -3.0 pC. What is the magnitude of the electric field 2.0 cm from the center of these conductors?
 a. 23 N/C
  b. zero
  c. 45 N/C
  d. 90 N/C
  e. 110 N/C
