The electrons will transfer from the cup to the metal can, causing both the cup and can to have a negative charge.

Answer 1

When the rod touches the foam cup, the electrons will transfer from the rod to the cup, causing the cup to become negatively charged. Therefore, the correct response is:

The electrons will transfer to the cup and will remain in a concentrated, negatively charged area on the cup where the rod was placed.

This outcome happens because the negatively charged electrons from the rod move to the neutral or positively charged cup, creating an area of negative charge on the cup.
