An electron with velocity v = 2.0  106 m/s is sent between the plates of a capacitor where the electric field is E = 200 V/m. If the distance the electron travels through the field is 1.0 cm, how far is it deviated (Y) in its path when it emerges from the electric field? (me = 9.1  1031 kg, e = 1.6  1019 C)
 
   
  a.
  0.84 mm
   
  b.
  0.44 mm
   
  c.
  0.44 cm
   
  d.
  0.84 cm
   
  e.
  1.4 mm

Question 2

There is a hollow, conducting, uncharged sphere with a negative charge inside the sphere. Consider the electrical potential at the inner and outer surfaces of the sphere. Which of the following is true?
   


   
  a.
  The potential on the inner surface is greater.
   
  b.
  The potential on the outer surface is greater.
   
  c.
  The potentials on both surfaces are zero.
   
  d.
  The potentials on both surfaces are equal but not zero.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
