A horizontal insulating rod with negative charge signs along its length is placed to the left of a neutral conducting sphere. The sphere is supported by a thin vertical insulating cylinder resting on a flat ground line. The rod is close to the sphere but does not touch it. No other labels, lines, text, or axes appear.
A negatively charged rod held near an uncharged conducting sphere.
An uncharged conducting sphere is mounted on an insulating stand. A negatively charged rod is brought near the left side of the sphere without making contact. Which choice correctly identifies the sign of the charge on the left side of the sphere and the total net charge of the sphere while the rod remains held in this position?
