Hiro rubs an inflated balloon on his hair, and his hair sticks to the balloon. As he moves the balloon away from his head, how does the electric force change?

The electric force between charged objects becomes weaker as the distance between them increases. As Hiro moves the balloon away from his head, the separation between the balloon and his hair grows, so the force decreases. The correct choice is C, “The electric force decreases because the distance increases.”
