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.
This is a photograph of what occurred as the canisters were moved toward each other. Which of these conclusions is
NOT accurate
A)
The pieces of tape have like charges.
Eliminate
B)
The charged pieces of tape exert a force on each other.
Because the pieces of tape have like charges they will repel each other.
D)
The closer the canisters get, the less likely the pieces of tape will repel.
