Q1:

A muon has a mass of 106 MeV/c². What is the minimum energy of a photon that can produce a muon and an antimuon via pair production? Give your answer in mega-electron volts.

Q2:

An electron has a mass of 511 keV/c². What would the energy of a photon that was produced from the annihilation of an electron and a positron be? Assume that the kinetic energy of the two particles is negligible. Give your answer in kilo-electron volts.

Q3:

A tauon has a mass of and a muon has a mass of . What is the ratio of the mass of a tauon to the mass of a muon? Give your answer to two decimal places.
