Answers
Answer:
Materials
Hard-rubber comb
Glass rod
Piece of silk or nylon
Two pieces of polystyrene foam
Two pieces of string or thread
Ring stand and ring
Aluminum foil
Paper
Towel
Procedure
Safety Note: Electrostatic forces are very sensitive to the environment. As you conduct this activity, be careful not to get fingerprints on the materials. Do not allow the materials to touch your clothing. Make sure classroom windows are closed. Because humidity greatly affects electrostatic forces, conduct the activity in an air-conditioned room. Do not conduct this activity on a metal table. You may have to repeat each step several times, taking these precautions each time.
Clean the hard-rubber comb and glass rob. Remove all of the water with a towel.
Tear up the paper into tiny pieces. Make a small pile of the pieces of paper.
Produce a negative (–) charge on the comb by rapidly passing it through dry, greaseless hair (straight hair works best). Bring the charged comb near the pile. Record what you observe.
Produce a positive (+) charge on a glass rod by rapidly rubbing it with silk or nylon. Bring the charged rod near the pile. Record what you observe.
