8. When a negatively charged balloon is placed against a non-conducting wall, positive charges in the wall are __ neutralized too bound to negative charges in the wall to have any effect. repelled by the balloon. attracted to the balloon

## Step 1<br />The problem involves the interaction between a negatively charged balloon and a non-conducting wall. The balloon, being negatively charged, creates an electric field around it.<br /><br />## Step 2<br />The wall, being non-conducting, has positive charges that are bound to their respective atoms. These positive charges are not free to move around.<br /><br />## Step 3<br />Despite the positive charges being bound to their atoms, they are still influenced by the electric field created by the negatively charged balloon. This is because the electric field can induce a polarization in the wall, where the positive charges are attracted towards the balloon.<br /><br />## Step 4<br />The attraction between the positive charges in the wall and the negatively charged balloon is due to the principle of electrostatics, which states that opposite charges attract each other.
