One of the unstable isotopes of caesium undergoes beta decay, as a result of which it turns into an isotope of Barium, with the simultaneous emission of an electron and a neutrino. The Caesium isotope is 1.18 Mev/c^2 more massive than the Barium isotope.(adsbygoogle = window.adsbygoogle || []).push({});

Assuming that the initial and final isotopes are produced at rest , how much kinetic energy is carried of by the electron and neutrino? Explain why this must be equal to

T+cp

where T is the kinetic energy of the electron and p is the magnitude of its momentum

Use the result to determine the value of T

I have No idea at all what to do so any help at all would be greatly appreciated

(rest mass of electron=0.511Mev/c^2 and neutrino assume massless)
