Calculate Potential Energy of Electron in Bohr Model

Click For Summary

Homework Help Overview

The discussion revolves around calculating the potential energy of an electron in the context of the Bohr model, specifically when moving from infinity to a distance r from the nucleus.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the use of electric charge and potential difference in calculating energy gain. There is mention of the Coulomb potential and the reference point of zero potential at infinity. Questions arise regarding the specific integral needed for the calculation.

Discussion Status

The discussion is ongoing, with some participants providing guidance on concepts and approaches, while others express confusion and seek clarification on prerequisites and the integral involved.

Contextual Notes

There is a suggestion that knowledge of classical electromagnetism may be necessary for understanding the problem, indicating a potential gap in background knowledge among participants.

How can I calculate the potential energy of the electron when we bring it from the infinity to the distance r?
 
Physics news on Phys.org
-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?

Zz.
 
I am pretty confused on it.
