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.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
