Static Electricity: Stationary Charges (page 2)
Try New Approaches
- Does the material from which the bobs are made affect the time they stay charged after the balloon is removed? Repeat the experiment using different materials, such as Styrofoam, cotton, and aluminum foil, to make the bobs.
- How would using a positively charged object affect the results? Since the balloon attracted the electrons from the wool scarf, the scarf becomes positively charged. Repeat the original experiment, again rubbing the balloon with the scarf, but this time using the scarf instead of the balloon to charge the bobs.
Design Your Own Experiment
- Charging by conduction is the process of electrically charging a neutral body by touching it with a charged body. Design a way to charge a body by conduction. One way would be to use the procedure from the original experiment, but this time instead of just holding the charged balloon near the bobs, touch the charged balloon to the two bobs for 1 to 2 seconds. Determine the time it takes for the bobs t
