A positively charged rubber rod is moved close to a neutral copper ball that is resting on a nonconductin sheet of plastic. (a) Show how the charges are arranged on these spheres if they are very far from each other. (b) If the sphere's are now broght close to each other, but do not touch, sketch how the charges will be distributed on their surfaces. (c) In part (b), show how the charges would be distribued if both spheres were negative.
