Calculating Separation between Nucleus Fragments: Nuclear Physics Problem"

[neelakash]

Homework Statement

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.

Homework Equations

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.

 

[Meir Achuz]

But you need to know the separation to find the Coulomb repulsion.
Use the formula for R=1.2A^(1/3) to find each radius.

is that really necessary?we are interested about the central distance...
