A balloon and a section of a wall both have neutral charges, as shown below.
A student rubs his hair on the balloon, giving it a negative charge. How will the charges be arranged in the wall when it is placed near the negatively changed balloon?
(1 point)
The wall will have its positive charges on the side closer to the balloon
The wall will now have all positive charges and no negative charges
The charges in the wall will not change or rearrange at all.
The wall will have negative charges on the the side closer to the balloon

The first choice.
The balloon's negative charge induces polarization in the neutral wall: negative charges are driven slightly away (or the electron clouds shift), leaving an excess of positive charge on the wall surface nearest the balloon and negative farther away. This induced positive region causes attraction.
