Hi all,
I am reading the retarded potentials in electrodynamics and I have a question about the classical Bohr model. I am wondering what would be the acceleration of an electron orbiting around a proton (in Hydrogen atom for example). Having the information that the angular momentum of the electron is h[itex]\hat{e}[/itex]_z and that the frequency is [itex]\omega[/itex], how can I find the acceleration (as a vector)?
