In the limitations of Rutherford atom model, it is said that electrons would radiate energy and fall to the nucleus if it rotates in any path other than the allowed circular path.
I want to ask, how does an accelerating electron radiate energy and how does it not radiate energy in allowed paths? I mean , in a circular path , displacement is perpendicular to force and so work done is zero . Then, how does it lose energy ...?
[Any conceptual explanation would be helpful.]
