2) Two uncharged spheres with their conducting surfaces in contact are supported on a large wooden table by insulated stands. A positively charged rod is brought up close to the surface of one of the spheres on the side opposite to its point of contact with the other sphere. a) Describe the induced charges on the two conducting spheres and sketch the charge distributions on them. b) The two spheres are separated far apart, and the charged rod is removed. Sketch the charge distributions on the separated spheres. c) Can the same rod be used to give one sphere a positive charge and another sphere a negative charge without the rod having to be recharged? Explain why or why not.
