Reading a thread in relativity I would like to know more precisely about radiation from charge. 1 I put a charge on the table of my house. Gravity and table reaction force work on the charge. They cancel so net force does not work on the charge, thus no-force no-velocity cause no radiation. Am I right ? 2 A charge is put on the Earth that rotates around the Sun. Does synchrotron radiation by rotation motion take place ? Does it takes place but in non measurable tiny amount ? 3 Say a charge is free falling attracted by gravity of an electrically neutral planet, radiation takes place from a charge due to acceleration motion. But in co-moving local frame of reference with the charge, nothing particular including radiation would take place. How do we conciliate these views?
