Total energy
E = Ȗmc^2
E = total energy
Ȗ = Lorentz factor
m = rest mass
c = speed of light
When a proton and antiproton
collide, they annihilate each
other and their mass energy is
converted into a pair of gamma
ray photons. Calculate the total
energy of the gamma rays.
E = Ȗmc^2
E = (70.7)(938 MeV/c^2 )c^2
E = 6.63×10^4 MeV
2 E = 1.33×10^5 MeV
