Opposite charges attract! Like charges repel!
This is a kind of electroscope student made in science class to study charges.
Student Procedure:
~Tear off two pieces of tape, each 4 inches (10 cm) long.
~Press each piece firmly on the work table leaving one end of each tape piece sticking up as a handle.
~Quickly pull the tapes from the table and stick one piece on the arm of a straw in one film canister, and the other piece on the arm of a straw in the other film canister.
~Move the canisters so the two pieces of tape are face to face, about 6 inches apart.
~Slowly move the canisters closer together.
~Notice that the two tapes repel each other.
Ms. Mann tore off a another piece of tape and pressed the tape firmly on her lab bench. As she was pulling the piece of tape "up" she ripped a second piece of tape from the dispenser.

What would be a logical argument about how the pieces of tape Ms. Mann prepared would behave? Explain.
