A neutral plastic strip is rubbed with cotton and acquires a positive charge. Which of the following statements are true of the positively-charged strip? It lost some electrons to the cotton during the charging process. It lost all of its electrons to the cotton during the charging process. It has the opposite charge as the cotton. It would now be repelled by the piece of cotton which was used to charge it. It gained protons during the rubbing process. As a material, plastic has a greater affinity for electrons than cotton. It could exert either a repulsive or attractive influence upon neutral paper bits. It has an excess of protons compared to the number of electrons. It could be used to charge an electroscope negatively by the process of induction. It lost negative electrons and gained positive electrons during the charging process. It lost neutrons during the charging process (or at the very least, its neutrons became ineffective).
