Question

review it!
taylor rubbed a balloon on her hair and then stuck it to the wall.
select the statement that best explains why the balloon sticks to the wall.
the wall and the balloon both have a negative charge.
the wall has no charge and the balloon has no charge.
the wall and the balloon both have a positive charge.
the wall has a positive charge and the balloon has a negative charge.

Explanation:

When Taylor rubs the balloon on her hair, electrons are transferred from her hair to the balloon. So the balloon has a negative charge. The wall is neutral initially. But when the negatively - charged balloon is brought near the wall, it induces a positive charge on the surface of the wall (due to electrostatic induction). Opposite charges attract each other. So the balloon (negative charge) is attracted to the wall (induced positive charge).

Answer:

The wall has a positive charge and the balloon has a negative charge.
