A long cylinder (radius = 3.0 cm) is filled with a nonconducting material which carries a uniform charge density of 1.3 mC/m3 . Determine the electric flux through a spherical surface (radius = 2.0 cm) which has a point on the axis of the cylinder as its center.
 a. 5.7 N  m2/C
  b. 4.9 N  m2/C
  c. 6.4 N  m2/C
  d. 7.2 N  m2/C
  e. 15 N  m2/C

Question 2

The xy plane is painted with a uniform surface charge density which is equal to 40 nC/m2 . Consider a spherical surface with a 4.0-cm radius that has a point in the xy plane as its center. What is the electric flux through that part of the spherical surface for which z > 0?
 a. 14 N  m2/C
  b. 11 N  m2/C
  c. 17 N  m2/C
  d. 20 N  m2/C
  e. 23 N  m2/C
