It is my understanding that if we have a charge at rest on earth, a free falling observer will see it radiating, as the charge is in an accelerated frame of reference. This observer can in principle collect this radiation and so he will be slowed down by the radiation pressure.
How an observer at rest on earth will explain this deceleration, what force is responsible for it in his frame of reference, where the charge is not radiating? (I have heard that rindler horizons prevent the observer at earth from seeing the radiation, but this is not convincing to me because the free falling observer is in principle outside of the rindler horizon, as he is perfectly visible from the earth's surface).
