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. 23 N/C
  b. zero
  c. 45 N/C
  d. 90 N/C

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
