Sensory Evaluation

The figure shows a negatively charged sphere and a balloon that has been rubbed with dry human hair. If the two are brought close to each other but do not touch each other, you can predict that the objects will

Repel Each Other

the human hair is negatively charged. When the sphere is rubbed against the human hair, it becomes negatively charged. It is electrostatically induced. When the balloon is rubbed against the human hair, it becomes negatively charged as well.
