An infinite plane of charge with is tilted at a 45 angle to the vertical direction as shown below. The potential difference, V_B  V_A, in volts, between points A and B, a 4.50 m distance apart, is
 
 
 
   
  a.
  7.06.
   
  b.
  9.98.
   
  c.
  14.11.
   
  d.
  +7.06.
   
  e.
  +9.98.

Question 2

Four electrons move from point A to point B in a uniform electric field as shown below. Rank the electrons in diagrams I through IV by the changes in potential from most positive to most negative when traveling from A to B.
 
   

   
  a.
  I = II = III = IV.
   
  b.
  II = III > I > IV.
   
  c.
  III > I = IV > II.
   
  d.
  II > I = IV > III.
   
  e.
  I > II = III > IV.
