Question

in this image, the child rubbed the balloon on her hair and now there is an attraction between the hair and the balloon. the mechanism for this system is at a scale we cannot see. which statement best describes the mechanism for why the balloon is attracted to the childs hair? protons from the balloon moved to the hair, resulting in an attraction between oppositely charged objects. atoms from the hair moved to the balloon, resulting in an attraction between oppositely charged objects. electrons from the hair moved to the balloon, resulting in a repulsion between objects with the same charge. electrons from the hair moved to the balloon, resulting in an attraction between oppositely charged objects.

Explanation:

When a balloon is rubbed on hair, electrons are transferred from the hair to the balloon. This makes the balloon negatively - charged and the hair positively - charged. Oppositely charged objects attract each other. Protons do not move during this process as they are in the nucleus of an atom and are tightly bound. Atoms do not move as a whole in this static - electricity phenomenon. Also, the interaction here is attraction between opposite charges, not repulsion between like charges.

Answer:

Electrons from the hair moved to the balloon, resulting in an attraction between oppositely charged objects.
