Given information
Given a decay such that the pion decays from rest and mass of neutrino is 0. We are asked to find the kinetic energy of the positron.
Step-by-step explanation
Step 1.
According to the conservation of energy;
But, given that pion decays from rest; ie, momentum of the pion is zero. And applying conservation of momentum;
