Question 1
A photon with an energy of Eγ = 2.090 0 GeV creates a proton-antiproton pair in which the proton has a kinetic energy of 95.0 MeV. What is the kinetic energy of the antiproton? (mpc2 = 938.3 MeV)
Question 2
Calculate the range of the force that might be produced by the virtual exchange of a proton. (mp = 1.67 × 10−27 kg, h = 6.626 × 10−34 J ⋅ s)
