SUMMARY
The discussion centers on the paradox in classical electrodynamics regarding a charged particle falling under gravity. The Larmor formula indicates that the power radiated by the charge is proportional to the square of the acceleration (g²), while the Abraham-Lorentz formula, which accounts for radiation reaction, yields zero due to its dependence on the time derivative of acceleration. This discrepancy highlights the limitations of the Abraham-Lorentz formula in scenarios involving constant acceleration, such as a gravitational field.
