Answer:
the final particle energy is proportional to
![Emax \infty\ R^2](https://img.qammunity.org/2021/formulas/physics/college/df5l9p4chtjolcipdffdo8hvix5n6y9nhm.png)
Step-by-step explanation:
The computation of the final particle energy is as follows;
As we know that
Energy is respect with the radious as
![Emax = (q^2R^2B^2)/(2m)](https://img.qammunity.org/2021/formulas/physics/college/4tv5fxkflab4c1gelcvei6zfqnkgyl2bgf.png)
In the case when other quantities would remains the same or constant
So, the final particle energy is proportional to
![Emax \infty\ R^2](https://img.qammunity.org/2021/formulas/physics/college/df5l9p4chtjolcipdffdo8hvix5n6y9nhm.png)
The same is to be considered and relevant too
