Question
The masses of the neutrinos are still not precisely determined, but let us assume for the purpose of this problem that the mass of an electron neutrino is one millionth the mass of an electron. What is the kinetic energy, in eV, of an electron neutrino moving at 0.954? please help!! The masses of the neutrinos are still not precisely determined, but let us assume for the purpose of this problem that the mass of an electron neutrino is one millionth the mass of an electron. What is the kinetic energy, in eV, of an electron neutrino moving at 0.954? please help!!Explanation / Answer
= E0 / (1 - (v/c)^2)^1/2
energy of the electron nutreno=E0 / (1 - .954^2)^1/2 = 3.335 E0
Ek = E - E0 =2.3335 E0
The rest energy of the electron is .511MeV
The rest energy of the neutrino = .511 eV (1 millionth of the electron)
