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.
