Modified True or False. Write True if the statement is true, otherwise write False and change the underlined word(s) to make the statement true. An insulator offers no resistance to the flow of charges below some critical temperatures. In charging by conduction, the acquired charge is the same as that of the charging body. " The charge of a body must be integral multiples of e" means that the charge is conserved. A neutral body charged by induction using a positively charged body becomes negatively charged.
The figure shows a small positive charge some distance away from a larger positive charge. The smaller charge is currently a distance r₁ away from the center of the larger charge. The radius r₁ is twice as far away from the larger charge as 12. Answer the three questions below using three sig figs. S r.
