A5. A6. A7. A8. Objects may be charged by conduction with a previously charged object. When so electrified (actual, no actual) contact between the bodies is required and in the process the charging body (contributes, does not contribute) some of its charge to the other body; therefore, the charging body (may, will) have less mass. Objects may be charged by induction from a previously charged object. For this process the charge assumed by the charged object is the (same, opposite) sign as that of the charging object. Given a certain electric charge there (will, will not) be any influence felt outside the metal conductor, if the charge is placed inside a metal conductor. If this charge is placed on a hollow metal conductor it (will, will not) produce any influence inside the conductor, and it (will, will not) produce any effect outside the conductor. One of the above items is not supported (nor contradicted) by our observations in today's Whic
