Question
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 ?3Q; and sphere C has a net charge of +7Q. 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. Assuming no charge is transferred to you, what is the total combined charge on the three spheres at the end of the process?Explanation / Answer
Qa = 5.5 q Qb = 4.625 q Qc = 4.625q
