Since the rest energy of an electron and its antiparticle a positron is 0.511 MeV, a gamma ray must have an energy larger than 1.022 MeV to produce an electron-positron pair.
  Indicate whether the statement is true or false

Question 2

Because of the equivalence of energy and mass, a gamma ray, which is a high energy photon, can disappear, and in its place there will be produced an electron and a positron, which both have mass.
  Indicate whether the statement is true or false
