Homework # 16 Electric Charge Handout Problems: 1: How does the election theory explain (a) why a rubber rod becomes negatively charged when rubbed with for; (b) why a glass rod becomes positively charged when rubbed with silk? 2. A positively charged body attracts object A and repels object B. What conclusions can be drawn about the charge present on each object from these observations? . \\ 3. The diagram below shows the initial charge and position of three metal spheres, [K Y, & Z. +12 0 0 ' SphereX is brought into contact with sphere Y and then removed. Then sphere Y is brought into contact with sphere Z and removed. What is the charge on each sphere after this procedure is completed? Show your work. 4. If all three spheres of the above question were brought together, and then moved apart at the same time, what would the charge on each be? 5. What would your answer to the previous question have been if the three spheres Were insulators, not metal conductors? _H_h_______
