Question 2

Suppose you were to try to create a proton-antiproton pair by annihilation of two very high-energy gamma rays of the same wavelength heading toward each other. The proton and the anti-proton have the same masses, but opposite charges.
 
  What would be the minimum energy needed for each photon? (e = 1.60  10-19 C, mproton = 1.67  10-27 kg, c = 3.00  108 m/s)
  A) 223 MeV B) 1880 MeV C) 12.2 MeV D) 1.022 MeV E) 939 MeV
