A scientist wipes a rubber rod with a wool cloth which leads to a negative charge on the rod. After this, the scientist touches the rod to a neutral metal sphere. This will transfer the negative charges from the rod to the sphere: Which statement explains what will happen to the negative charge, and why? (1 point) Responses It will spread uniformly over the surface of the sphere, because of the conducting nature of the sphere and similar charges push away from each other. It will spread uniformly over the surface of the sphere, because of the conducting nature of the sphere and similar charges push away from each other. It will only spread to the air around the sphere, because negative charges need to occupy a big area. It will only spread to the air around the sphere, because negative charges need to occupy a big area. It will remain only on one spot of the sphere, because the low conductivity of the metal prevents the charges from spreading out. It will remain only on one spot of the sphere, because the low conductivity of the metal prevents the charges from spreading out. It will slowly move to the bottom of the sphere, because the charges are heavy and will sink to the bottom.
The correct statement is: It will spread uniformly over the surface of the sphere, because of the conducting nature of the sphere and similar charges push away from each other.
This is because the metal sphere is a conductor, which means that electrons can move freely within it. When the negatively charged rod is touched to the sphere, the negative charges will spread out evenly over the surface of the sphere due to the repulsion between like charges.
