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
