2. For an electron and a neutron with two conditions of kinetic energies: KE=1.0 MeV and 1.0 GeV (M=106, G=109), calculate the momentum P, de-Broglie wavelength 
, the particle velocity , and phase velocity 
(A) For an electron with KE= 1.0 MeV, P = 8.426 MeV Ic, 
, 
= 1.5155x108m/s
(B) For an electron with KE= 1.0 GeV, P = 266.44 MeV Ic, 
, 
= 4.7925×106m/s
(C) For a neutron with KE= 1.0 GeV, P = 11.43 GeV / c, 
, 
= 2.0553 x108m/s
(D) For a neutron with KE= 1.0 MeV, P = 361.34 MeV Ic, 
, v=1.3829×107 mls
(E) For a neutron with KE=1.0 GeV, P =1.697 GeV I c, 
, v=2.6226x108m/s
