The wall will have negative charges on the the side closer to the balloon
The wall will have negative charges on the the side closer to the balloon

The wall will have its positive charges on the side closer to the balloon
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 wall will now have all positive charges and no negative charges

The charges in the wall will not change or rearrange at all.

When a negatively charged balloon is brought near a neutral wall, the charges in the wall will rearrange due to the phenomenon of polarization. The negative charges in the wall will be repelled by the balloon, while the positive charges will be attracted to it.

As a result, the side of the wall that is closer to the balloon will have a concentration of positive charges, while the side farther from the balloon remains neutral or less positively charged.

Therefore, the correct response is:

The wall will have its positive charges on the side closer to the balloon.
