If Jack touches a negatively charged plastic rod to a metal sphere, several things can happen depending on the conditions. Here are a few possibilities:
1. Charge Distribution: The negative charge from the plastic rod may transfer to the metal sphere. This happens because like charges repel each other, so the negative charges on the rod move away from each other and redistribute on the metal sphere.
2. Neutralization: If the metal sphere is initially neutral (without any charge), touching it with the negatively charged plastic rod will make it negatively charged. This occurs due to the transfer of electrons from the rod to the sphere, resulting in an excess of negative charge on the sphere.
3. Grounding: If the metal sphere is grounded, touching the negatively charged plastic rod to it will cause the excess negative charge to flow into the ground. This grounding process neutralizes the charge on the sphere by allowing the charges to distribute across the Earth's conductive surface.
Overall, the exact outcome depends on the charge and proximity of the rod to the sphere, as well as the conductivity of the sphere and any surrounding objects.
