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 $$e*\Delta U$$. (e = electric charge, $$\Delta V$$ = 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.
