What will happen to the negatively charged electrons when the rod touches the foam cup? (1 point) Responses The electrons will transfer from the cup to the metal can, causing both cup and can to have a positive charge. The electrons will transfer from the cup to the metal can, causing both cup and can to have a positive charge. The electrons will transfer from the cup to the metal can, causing both the cup and can to have a negative charge. The electrons will transfer from the cup to the metal can, causing both the cup and can to have a negative charge. The electrons will transfer to the cup and will remain in a concentrated, negatively charged area on the cup where the rod was placed. The electrons will transfer to the cup and will remain in a concentrated, negatively charged area on the cup where the rod was placed. The electrons will transfer to the cup and will remain in a concentrated, positively charged area on the cup where the rod was placed.

Answer 1

When the rod, which is negatively charged, touches the foam cup, the negatively charged electrons from the rod will transfer to the cup. This transfer will result in the foam cup becoming negatively charged as well, since it gains excess electrons. 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.
