Question: 1 an electron of mass me 0511 mevc2 is...

Question details

1. An electron of mass me = 0.511 MeV/c2 is travelling in water, which has a refractive index n = 1.33. To produce the Cherenkov effect, calculate the smallest kinetic energy that the electron must have in units of MeV.

(b) For a muon of mass mµ = 105.7 MeV/c2 travelling in water at the same speed as the electron from part (a), calculate its kinetic energy in units of MeV.
