A velocity selector uses a fixed electric field of magnitude E and the magnetic field is varied to select particles of various energies. If a magnetic field of magnitude B is used to select a particle of a certain energy and mass, what magnitude of magnetic field is needed to select a particle of equal mass but twice the energy?
 a. 0.50 B
  b. 1.4 B
  c. 2.0 B
  d. 0.71 B
  e. 1.7 B

Question 2

What value of B should be used in a velocity selector to separate out 2.0-keV protons if E is fixed at 80 kV/m?
 a. 0.18 T
  b. 0.11 T
  c. 0.15 T
  d. 0.13 T
