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.

Question

How do the electrons move?
(1 point)
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 one negatively charged spot and not spread out. This is because the styrofoam cup is an insulator.
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 electrons will move and spread out through the cup and to the can. This is because the styrofoam cup is a conductor.

Answer 1

The correct answer is:

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

Explanation: When the negatively charged balloon touches the metal can, the electrons from the balloon can move into the metal can because metal is a conductor. From the can, the electrons can spread out, potentially affecting the styrofoam cup as well, but the key point is that the electrons will first move through the can due to its conductive nature. The styrofoam cup, being an insulator, will not allow the flow of electrons directly but can still have some influence once the can is negatively charged.
