A 4.0-pC point charge is placed at the center of a hollow (inner radius = 2.0 cm, outer radius = 4.0 cm) conducting sphere which has a net charge of 4.0 pC. Determine the magnitude of the electric field at a point which is 6.0 cm from the point charge.
 a. 35 N/C
  b. 25 N/C
  c. 30 N/C
  d. 20 N/C
  e. 10 N/C

Question 2

Charge of uniform density (40 pC/m2) is distributed on a spherical surface (radius = 1.0 cm), and a second concentric spherical surface (radius = 3.0 cm) carries a uniform charge density of 60 pC/m2 . What is the magnitude of the electric field at a point 2.0 cm from the center of the two surfaces?
 a. 1.1 N/C
  b. 4.5 N/C
  c. 1.4 N/C
  d. 5.6 N/C
  e. 0.50 N/C

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
