5. Question
Two identical conducting spheres are mounted on insulating handles, as shown. Sphere I has a positive charge, and sphere II has no excess charge, as shown in Figure 1. Sphere I is brought close to sphere II, which is grounded with a wire, as shown in Figure 2. The grounding wire is disconnected and then sphere I is removed, isolating sphere II as shown in Figure 3. Which of the following correctly predicts the charge on sphere II after this procedure is followed?
