If a charge is resting on a table (as I believe the original query was phrased) in a graviataional field, then (ignoring rotation of the Earth) it is at rest, NOT being accelerated. Gravity pulls down, the table pushes up. Acceleration of a charge WILL cause it to radiate, whether said acceleration is due to gravity, magnetic fields, fusion rockets or telekinesis. You don't need to drag Minkowski into it. -- Berry Kercheval Zehntel Inc. (ihnp4!zehntel!zinfandel!berry) (415)932-6900
