A hard rubber rod is rubbed with wool and is thus negatively charged. The charged rubber rod is then scraped along one end of an initially uncharged acrylic rod suspended from a plastic string. The rubber rod is then moved far away from the acrylic rod. The acrylic rod is an insulator (i. e., charge is not free to move through the acrylic). Which of the following best represents the charge distribution on the acrylic rod after the rubber rod is moved far away from the acrylic rod? 1) No charge 2) positive charge at the end it was rubbed on 3) negative charge at the end it was rubbed on 4) positive charge throughout 5) Negative charge throughout 6) Negative at one end and positive at the other Is the net charge on the acrylic rod positive, negative, or zero? When the rubber rod was scraped, the net charge on the rubber rod changed or remained the same?
