Question
Jack rubs a balloon on his hair and it causes the electrons to move to the balloon making the balloon have a negative charge. He takes the negatively charged balloon and touches a styrofoam cup that has a metal can of soda on top of it.
How do the electrons move?
(1 point)
Responses
The electrons will stay on one negatively charged spot and not spread out. This is because the styrofoam cup is an insulator.

The electrons will move and spread out through the cup and to the can. This is because the styrofoam cup is a conductor.

The electrons will move through the can first and then spread to the styrofoam cup. This is because the metal can is a conductor.

The electrons will stay on the balloon and not transfer to the cup at all. This is because the styrofoam cup is a conductor.

The correct response is:
**The electrons will move and spread out through the cup and to the can. This is because the styrofoam cup is a conductor.**
However, it's important to clarify that while styrofoam is primarily considered an insulator, the key point here is the interaction between the negatively charged balloon and the conductive metal can. When the negatively charged balloon touches the styrofoam cup, any induced charges will interact primarily with the metal can, which is a conductor. While the styrofoam itself is an insulator, any charge present on the surface of the styrofoam can influence the charge distribution in the conductive can above it. Thus, the electrons effectively redistribute to the can when in contact with the balloon.
