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

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
