Exploring Electrostatics July 6, 2009 Interactions of Scotch Tape Strips Questions 1) When the tape is peeled off the table and the non-sticky side of the tape was brought  toward my partner’s strip, they don’t touch. They repel. The closer the pieces of tapes  were, the more repulsion. 2) The interaction between two top strips when they were brought together was that they  repelled. The interaction between two bottom strips when they were brought together  was that they repelled as well. The interaction between a top and a bottom strip was that  they were attracted. The top side was positive; the bottom side was negative. 3) The observations of the tape strip interactions are consistent with the hypothesis that  there are two different types of charge. In physics, we learned that two same charges will  repel, and two different charges will repel, and this experiment verified this concept. Identifying Charge Questions 1) When the rubber rod was charged and brought near but not touching the electroscope,  the aluminum foil strip in the electroscope raises. 2) The rubber rod touching the electroscope makes the aluminum foil raise to a point, and it  will stay there. 3)
