The graph in the figure shows the electric field strength (not the field lines) as a function of distance from the center for a pair of concentric uniformly charged spheres.
 
  Which of the following situations could the graph plausibly represent? (There may be more than one correct choice.)
 
  A) a positively charged conducting sphere within another positively charged conducting sphere
  B) a positively charged conducting sphere within an uncharged conducting sphere
  C) a solid nonconducting sphere, uniformly charged throughout its volume, inside of a positively charged conducting sphere
  D) a positively charged nonconducting thin-walled spherical shell inside of a positively charged conducting sphere
  E) a positively charged nonconducting thin-walled spherical shell inside of another positively charged nonconducting thin-walled spherical shell

Question 2

The electric field strength in the space between two closely spaced parallel disks is .0  105 N/C. This field is the result of transferring 3.9  109 electrons from one disk to the other.
 
  What is the diameter of the disks? (e = 1.60  10-19 C, 0 = 8.85  10-12 C2/N  m2)
  A) 3.0 cm
  B) 1.5 cm
  C) 4.5 cm
  D) 6.0 cm
