Directions

After familiarizing yourself with the website, do the following:

• Predict what happens when a charged balloon is moved closer to the neutral wall. Draw a picture.
• After rubbing the balloon on the sweater, how does the charge on the balloon compare to the charge on the sweater? What happens to the positive charges? What happens to the negative charges? Draw a picture.
• Remove the wall, and use two balloons to explore attraction and repulsion. How do the +/- symbols help you decide whether something attracts or repels?
• Explain how a balloon can be strongly or weakly attracted to the sweater.

Submit your answers/drawings as instructed by your instructor.
