Ann is in an inertial frame. Bob is in a rocket accelerating relative
to Ann. Bob is holding a plastic rod bearing a net positive charge.
Is the charge radiating? Bob says no; Ann says yes. Who's right and
why?


Ann's right. Bob's wrong. Accelerating charges radiate.

This is probably a stupid question, because I'm having trouble
visualizing what's going on here: If the radiation that Ann sees is
scattered or reflected back to Bob, where does he say this radiation
comes from?
