You have three identical metal spheres that have different initial net charges. Sphere A has a net charge of +5Q; sphere B has a net charge of −2Q; and sphere C has a net charge of +8Q. You first touch sphere B to sphere A, and then separate them; you then touch sphere A to sphere C, and then separate them; and finally you touch sphere C to sphere B, and then separate them. (a) Assuming no charge is transferred to you, what is the total combined charge on the three spheres at the end of the process? Q (b) What is the charge on sphere A at the end of the process? Q (c) What is the charge on sphere B at the end of the process?
