A teacher places a metal can on top of an insulating foam cup and touches the side of the foam cup with a negatively charged rod. The setup is shown in the picture below.

Question

What will happen to the negatively charged electrons when the rod touches the metal can?

Responses

The electrons will transfer to the can because it is the conductor.
The electrons will transfer to the can because it is the conductor.

The electrons will transfer to the foam cup because it is an insulator.
The electrons will transfer to the foam cup because it is an insulator.

The electrons will transfer to the can because it is an insulator.
The electrons will transfer to the can because it is an insulator.

The electrons will transfer to the foam cup because it is a conductor.

Answer 1

The correct response is:

The electrons will transfer to the can because it is the conductor.

When the negatively charged rod touches the metal can, which is a conductor, the excess electrons from the rod will be transferred to the can. The foam cup is an insulator, so it will not allow the transfer of electrons through it.
