Homework Help: Bohr model of atom

  1. Apr 17, 2009 #1
    How can I calculate the potential energy of the electron when we bring it from the infinity to the distance r?

    -Use the fact that energy-gain when an electron moves from a to b is given by [tex]e*\Delta U[/tex]. (e = electric charge, [tex]\Delta V[/tex] = difference in potential).
    -Use the Coulomb potential for an atom.
    -Use the fact that the potential is set to zero at infinity.

    Good luck :)

    So we have to take the integral from infinity to "r" of what?

    Have you had classical E&M? I thought such course is a prerequisite for a modern physics/QM class?

    I am pretty confused on it.
