A balloon is rubbed with wool and sticks to a wall. Which statement best explains why the balloon sticks to the wall?

Explanation:
Rubbing with wool transfers electrons to the balloon, giving it a static electric charge. That charged balloon creates an electrostatic attraction with the neutral wall, so the balloon sticks to the wall. The wall doesn’t need to gain charge itself—the balloon’s charge interacts with the wall to produce the sticking force.
