You have four identical conducting spheres: A, B, C, and D. Sphere A starts with no net charge. The spheres B and C start with -1.00 C. Sphere D starts with 3.00 C. In the following events, if the spheres are not explicitly touching, you may assume they are held far away. First, A and B touch and are separated. Second, A and D touch and are separated. Third, D and C touch and are separated. What are the final charges on A-D? You may use an answer from the Answer Bank more than once.
