Consider below a single mnetal insulated sphere, (a) initially uncharged. When a negatively charged rod is nearby, (b), charges in the metal are separated. Electrons are repelled to the far side. When the sphere is touched with your finger. (c). electrons flow out of the sphere to Earth through your hand. The sphere is "grounded." Note the positive charge remaining (d) while the rod is still present and your finger removed, and (e) when the rod is removed. This is an example of charge induction by grounding. In this procedure the negative rod "gives" a positive charge to the sphere. The diagrams bolow show a similar procodure with a positive rod. Draw the correct charges for a through e.

A common demonstration involves charging a rubber balloon, which is an insulator, by rubbing it on your hair and then touching the balloon to a ceiling or wall, which is also an insulator. Because of the electrical attraction between the charged balloon and the neutral wall, the balloon slicks to the wall. Imagine now that we have two infinitely large, Hat sheets of insulating material. One is charged, and the other is neutral, lf these sheets are brought into contact, does an attractive force exist between them as there was for the balloon and the wall?
