A negatively charged balloon sticks to a wooden door. However, an uncharged balloon does not stick to a wooden door. What is the nature of the charge on the wooden door?
A. Electrically neutral
B. Positively charged
C. Conductor
D. Lacking protons
I am thinking it is A or B?
Its Definitely A.
Electrically neutral.
The door was neutral until the balloon came.
It is obviously neutral when the balloon is uncharged.

1. A negatively charged balloon sticks to a wooden door. However, an uncharged balloon does not stick to a wooden door. What is the nature of the charge on the wooden door?
To determine the nature of the charge on the wooden door, we can analyze the behavior of the negatively charged and uncharged balloons.
When a negatively charged balloon sticks to a wooden door, it suggests that there is an attraction between the balloon's negative charge and the charge on the door. This indicates that the wooden door has a positive charge. This eliminates options A and C, as an electrically neutral object or a conductor would not produce a positive charge that attracts the negatively charged balloon.
Therefore, the correct answer is B. The wooden door is positively charged.
It is important to note that since the door's positive charge attracts the negatively charged balloon, the door must have gained some electrons in order to acquire a positive charge. This can happen through a process called "charging by induction."
okay so it is B. positively charged
that's a neat website
