In problems involving electromagenetism it is often convenlent and informative to express answers in terms of a constant, `alpha`, which is a combination of the Coulomb constant, `k_(e) = 1//4piepsi_(0)`, the charge of the electron, e, and `h = h//2`, h being Planck\'s constant. For instant, the lowest energy that a hydrogen atom can have is given by `E = 1//2 alpha^(2) mc^(2)`, wherer m is the mass of the electron and c is the speed of light. Which of the following is the correct expression for `alpha`? (HINt : non-relativistic kinetic energy is `1//2 mv^(2)`, where v is speed.)
