Three insulating balls are suspended from thin threads. Various objects are then rubbed against other objects and each of the insulating balls is charged by touching them with one of these objects. In each case, be sure to discuss why you chose the answer you did. a. In one set of experiments, it is found that balls 1 and 2 repel each other and that balls 2 and 3 repel each other. From this we can conclude that i. 1 and 3 carry charges of opposite sign ii. 1 and 3 carry charges of the same sign iii. all three balls carry charges of the same sign iv. one of the objects carries no charge v. we need to do more experiments to determine the sign of the charges b. In a second set of experiments, it is found that balls 1 and 2 attract each other and that balls 2 and 3 repel each other. From this we can conclude that i. 1 and 3 carry charges of opposite sign ii. 1 and 3 carry charges of the same sign iii. all three balls carry charges of the same sign iv. one of the objects carries no charge v. we need to do more experiments to determine the sign of the charges.
