You are told that summed over both the surface areas of sphere A and sphere B below totals to . You can conclude that
 
 
 
   
  a.
  Sphere A contains charge q_in = Q.
   
  b.
  Sphere B contains charge q_in = Q.
   
  c.
  Sphere B contains charge q_in = +Q.
   
  d.
  Each sphere contains charge .
   
  e.
  The sum of the charges contained in both spheres is Q.

Question 2

An uncharged spherical conducting shell surrounds a charge q at the center of the shell. Then charge +3q is placed on the outside of the shell. When static equilibrium is reached, the charges on the inner and outer surfaces of the shell are, respectively,
   
  a.
  +q, q.
   
  b.
  q, +q.
   
  c.
  +q, +2q.
   
  d.
  +2q, +q.
   
  e.
  +3q, 0.
