A long nonconducting cylinder (radius = 6.0 mm) has a nonuniform volume charge density given by ar2, where a = 6.2 mC/m5 and r is the distance from the axis of the cylinder. What is the magnitude of the electric field at a point 2.0 mm from the axis?
 a. 1.4 N/C
  b. 1.6 N/C
  c. 1.8 N/C
  d. 2.0 N/C
  e. 5.4 N/C

Question 2

Each 2.0-m length of a long cylinder (radius = 4.0 mm) has a charge of 4.0 nC distributed uniformly throughout its volume. What is the magnitude of the electric field at a point 5.0 mm from the axis of the cylinder?
 a. 9.9 kN/C
  b. 8.1 kN/C
  c. 9.0 kN/C
  d. 7.2 kN/C
