Charging a PVC Pipe

Imagine charging up a simple PVC pipe by rubbing it with cloth, and then watching as it moves objects like a can without even touching them. This captivating phenomenon involves invisible forces. Charged objects can attract and repel, making making other objects move without direct contact. This phenomenon allows you to explore a very special type of movement and observe particles electrostatic force.

• GOT IT!

• I don't get it.

According to the Law of Conservation of Charge, what happens to the total charge in a closed system before and after the experiment is conducted?

• The total charge increases

• The total charge decreases

• The total charge remains constant

• The total charge becomes neutral

How does the distance between the charged PVC pipe and the can affect the strength of the force that moves the can?

• The force decreases with distance

• The force increases with distance

• The force remains constant

• Distance does not affect the force
