A negatively charged balloon sticks to a wooden door. However, an unchanged balloon does not stick to a wooden door. What is the nature of the charge on the wooden door?

Is it electrically neutral? Or could it possibly be possibly charged also?

The charge on the door must be electrically neutral.

If the door were positively or negatively charged, the electrons in the balloon would be repelled from or attracted to the door, making the overall charge on the door side of the balloon negative or positive, and then the balloon would stick to the door.

A negatively charged balloon sticks to the door because when it is pressed against the door, the electrons in the door are repelled from the electrons in the balloon. Thus, the door takes on a temporary positive charge (due to the lack of electrons which balance the charge) and the negatively charged balloon and positively charged door attract.

Oh YEAH! I thought about the attracting I just didn't think about the repelling.

THANKS :]

Based on the given information, if a negatively charged balloon sticks to a wooden door, it indicates that the wooden door is electrically neutral. This is because opposite charges attract each other, so the negative charge on the balloon is attracted to the positive charges present on the door's surface. If the door had a negative charge, the balloon would repel instead of sticking to it.

Based on the information provided, we can make the assumption that the wooden door is electrically neutral. Here's why:

When a negatively charged balloon sticks to a wooden door, it suggests that opposite charges attract each other. The negative charge on the balloon interacts with the positive charges in the wooden door, creating an attractive force that makes the balloon stick.

On the other hand, an unchanged (uncharged) balloon does not stick to the wooden door. This implies that there are no significant attractive or repulsive forces between the door and the balloon when both are uncharged.

Therefore, we can conclude that the wooden door is likely electrically neutral, meaning it has an equal number of positive and negative charges, resulting in no overall charge.
