The negative charges will spread out evenly throughout the metal sphere. This is because when the negatively charged plastic rod is touched to the sphere, some of the negative charges from the rod will be transferred to the sphere. Since metal is a good conductor of electricity, the electrons in the metal sphere will repel each other and spread out evenly to minimize the electrostatic repulsion. As a result, the negative charges will distribute themselves uniformly on the surface of the sphere. Therefore, the correct answer is: They spread out evenly.
The correct answer is "They spread out evenly." When Jack touches the negatively charged plastic rod to the metal sphere, the negative charges on the rod transfer to the metal sphere. Since like charges repel each other, the negative charges on the metal sphere will spread out as far apart as possible, which results in an even distribution of the charges throughout the sphere.
