2. If two protons lived in a universe where they were both far more massive than protons in our universe, but still had the same charge, calculate the mass that each proton would have if the gravitational force of attraction between them would exactly balance the electrostatic repulsion they experience. (Assume G and ɛ, are the same as in our universe and that the charge on each proton is 1.6 x 10-19 C.)

(a) A panicle and its antiparticle are at rest relative to an observer and annihilate (completely destroying both masses), creating two y rays of equal energy. What is the characteristic y -ray energy you would look for if searching for evidence of proton-antiproton annihilation? (The fact that such radiation is rarely observed is evidence that there is very little antimatter in the universe.) (b) How does this compare with the 0.511-MeV energy associated with electron-positron annihilation?

When a stat erupts in a supernova explosion, huge numbers of electron neutrinos are formed in nuclear reactions. Such neutrinos from the 1987A supernova in the relatively nearby Magellanic Cloud were observed within hours of the initial brightening, indicating they traveled to earth at approximately the speed of light. Explain how this date can be used to set an upper limit on the mass of the neutrino, noting that the mass is small the neutrinos could travel very close to the speed at light and have a reasonable energy (on the order of MeV).
