A positively charged rod is brought near an electroscope. Even though the rod does not touch the electroscope, the leaf of the electroscope deflects. Below, three students discuss this demonstration. Amadeo: "There are positive charges that jump from the rod to the plate of the electroscope. Since the electroscope is now charged, the leaf moves out." "Charges don't have to move from the rod to the plate to deflect. When the rod comes close, electrons in the electroscope move toward the plate. This leaves the bottom of the electroscope positively charged, and the leaf lifts." Barun: Carmen: "Positive charges are fixed in place. When the rod is brought close to the electroscope plate, the electrons in the plate are attracted and jump to the rod. This leaves the electroscope positively charged, and the leaf lifts."

When wool is rubbed against amber, the wool becomes positively charged and the amber becomes negatively charged. If you rub a glass rod with a silk cloth and an amber rod with a wool cloth, are the rods attracted to or repelled by each other? Are the cloths attracted to or repelled by each other? Is the silk cloth attracted to the amber rod or repelled by the amber rod? Is the wool cloth attracted to the glass rod or repelled by the glass rod? Explain your answers.

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 sticks to the wall. Imagine now that we have two infinitely large, flat sheets of insulating material. One is charged, and the other is neutral. If these sheets are brought into contact, does an attractive force exist between them as there was for the balloon and the wall?
