The pictures show a rod made of leather, a swatch of polystyrene, and an insulated ball of aluminum, all initially
uncharged. The rod is dragged across the polystyrene in order to transfer some charge. Label the signs of the electric
charge on the leather and the polystyrene.
Once the rod is charged, it is placed near the aluminum ball without making contact. Label the rod and the near and far
sides of the aluminum ball with the signs of their electric charges.

Expert Solution

Step 1

When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to be positively charged and the other object to be negatively charged.

Charging an object by bringing a charged object near to it but not actually touching the uncharged object is the process of charging by induction. Here the charges separate out on the surface of the uncharged object due to the presence of electrostatic force from the charged object near it.
