X-rays of energy 3.5 x eV scatter through an angle of 105 off of a free electron. What is the energy (in eV) of the scattered x-rays?
 
  (melectron = 9.11  10-31 kg, c = 3.00  108 m/s, h = 6.626  10-34 J  s, 1 eV = 1.60  10-19 J)

Question 2

A charged particle moving along the +x-axis enters a uniform magnetic field pointing along the +z-axis. Because of an electric field along the +y-axis, the charge particle does not change velocity. What is the sign of this particle?
 
  A) positive
  B) negative
  C) The particle could be either positive or negative.
