You are planning an investigation to demonstrate the concept of induction using a charged balloon and a neutral metal can.

Question

Which of the following steps should you include in your investigation plan? Select all that apply.

A.
Rub the balloon with animal fur to charge it negatively.

B.
Bring the charged balloon close to a neutral metal can without touching it.

C.
Touch the balloon to the metal can transfer electrons.

D.
Observe and record any movement of the metal can when the balloon is brought close.

E.
Measure the distance between the balloon and the can to ensure they do not touch.

Answer 1

To effectively demonstrate the concept of induction using a charged balloon and a neutral metal can, the following steps should be included in your investigation plan:

A. Rub the balloon with animal fur to charge it negatively.
B. Bring the charged balloon close to a neutral metal can without touching it.
D. Observe and record any movement of the metal can when the balloon is brought close.
E. Measure the distance between the balloon and the can to ensure they do not touch.

Step C, which involves touching the balloon to the metal can to transfer electrons, does not apply to the concept of induction. Induction involves the rearrangement of charges within the neutral object (the metal can) without direct contact.
