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, m proton = 1.67 × 10-27 kg, c =
3.00 × 108 m/s)
939 MeV
O1.022 MeV
O 12.2 MeV
O 1880 MeV
