Question
1a. Suppose that a plastic rod that has been rubbed with fur is used to charge both a metal-coated ball and a metal can. Mark the sign of the charges in the metal can and on the ball in the following diagram.
Possibly correct (the plastic rod is negative and the fur is postive correct me if I'm wrong. Then the plastic rod is discharged to the metal-coated ball and the metal can therefore making them temporaily negative)
1b. The charged ball is lowered into a metal can. If negative charges are free to move inside the can leaving positive charges unneutralized, what kind of excess charge will be on the inside of the can? What will move to the outside? Mark the sign of the charge on the ball and on the inside and the outside of the can.
Possibly correct (Ball=negative, can iniside = postive, can outside = negative)
1c. What will happen to the charges on the ball and the inside of the can if the ball touches the inside of the can? How about the charges on the outside of the can? Draw the location of the charges.
1d. Suppose that the ball is charged up again and brought near the can. Will it be attracted to or repelled from the outside of the can? Why or why not? Will it be attracted to the inside of the can? Why or why not?

1- A) It is given that, the plastic rod is negative charged,So, it will make the metal ball and the can negatively charged.
B) Now, when the charged ball is lowered into a metal can. If negative charges are free to move inside the can leaving positive charges unneutralized,then the inner surface of the can would be positively charged while the outer surface of the can would be negatively charged to make it neutral overall.
C) If the ball will touch the can then both the ball and the can will be negatively charged by the process of conduction. The negative charge of the ball will be distributed equivalently on both the objects.
D) It will repel the outer as well as the inner surface of the can because both the surface of can are negatively charged and also the ball is negatively charged.
