Question

a child rubs a balloon on her hair and now there is an attraction between the hair and the balloon. the mechanism for this system is static electricity. which statement best describes the mechanism for why the balloon is attracted to the childs hair? choose the best answer. a electrons from the hair moved to the balloon, resulting in an attraction between oppositely - charged objects. b protons from the balloon moved to the hair, resulting in an attraction between oppositely - charged objects. c protons from the hair moved to the balloon, resulting in an attraction between oppositely - charged objects. d electrons from the hair moved to the balloon, resulting in a repulsion between objects with the same charge.

Explanation:

When a balloon is rubbed on hair, electrons are transferred from the hair to the balloon. This leaves the hair positively - charged and the balloon negatively - charged. Oppositely charged objects attract each other. Protons do not move in this context as they are in the nucleus and not free to move like electrons. And the interaction is attraction, not repulsion.

Answer:

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