Charge Detector Construction Fabrication Procedure: Cut two strips of foil lcm by 4cm (1/3" by 1 1/2") Open out the paperclip to form the shape at right. You may want to experiment with fabrication option 2 or 3. (See figures below). Push the hook through the middle of the index card and tape so that it is at right angles to the card. Lay the two foil strips on top of one another and hang them on the hook by pushing the hook through them. Put this setup inside the jar so that the index card rests on top of the jar opening.
Charge Detector Operation Instructions Bring various charged objects near the top of the hook (above the index card and observe what happens. Notice what happens to the aluminum strips when the sources are pulled away from the top of the hook. What happens if the source actually touches the hook? If the strips do not fall back together, gently touch the hook with your finger.
Fabrication Option #1: Index Card Aluminum foil very tight fit Press the tops of the Aluminum strips together Keep small space between sheets at the bottom. Jar or glass
Fabrication Option #2: Jar or glass Index Card Aluminum foil fold in half very tight fit Press the bend in the Aluminum together Keep small space between sheets at the bottom.
Fabrication Option #3: Jar or glass Aluminum foil fold in half very tight fit Press the bend in the Aluminum together Keep small space between sheets at the bottom. Bend the aluminum strip in half and lay it over the paper clip like a towel on a rack.
Fabrication Option #4: Fabrication Procedure: 4 plastic drinking straws with flexible ends 2 plastic 35 mm film cans Enough modeling clay to fill the film cans halfway. A roll of 3-M Scotch Magic™ Tape, 3/4 inch (2 cm) width. (Don't substitute other brands of tape) A plastic comb and hair or a piece of wool cloth.
Extra electrons on the moving object pushed the electrons on the charge detector toward the bottom of the electroscope. Explanations The foil leaves at the bottom have a negative charge so they repel each other.
Explanations The lose of electrons made the moving object positive and the electrons on the charge detector move toward the top. The foil leaves at the bottom have a positive charge so they repel each other.
Extra electrons on the moving object pushed the electrons on the charge detector toward the bottom of the electroscope. Explanations The foil leaves at the bottom have a negative charge so they repel each other. When either charged object moves away, the electrons in the electroscope redistribute evenly so the leaves fall back down. The lose of electrons made the moving object positive and the electrons on the charge detector move toward the top. The foil leaves at the bottom have a positive charge so they repel each other. The observable behavior is the same, so we do not know what kind of charge was on the moving object.
Extra electrons on the moving object pushed the electrons on the charge detector toward the bottom of the electroscope. Explanations The foil leaves at the bottom have a negative charge so they repel each other. But we can state one part of Coulomb’s Law. The lose of electrons made the moving object positive and the electrons on the charge detector move toward the top. “Like charged particles repel each other” The foil leaves at the bottom have a positive charge so they repel each other. The observable behavior is the same, so we do not know what kind of charge was on the moving object.
