1. The problem statement, all variables and given/known data A nucleus[atomic no Z, mass no. A] splits into two fragments(z1,A1) and (Z2,A2).Find the separation between them at the time of splitting. 2. Relevant equations 3. The attempt at a solution I am giving the way I would approach.Please check and confirm: rest energy of (Z,A)=rest energy of (Z1,A1)+rest energy of (Z2,A2)+Coulomb repulsion term The Coulomb repulsion term includes the required separation. Please check if I am correct.
