Question

Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of 9q. Sphere B carries a charge of -q. Sphere C carries no net charge. Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Lastly, sphere C is touched to sphere B and separated from it. (a) What is the ratio of the final charge on sphere C to q

    Answer:

    Explanation:

    A and B are touched .

    charge on each of them after touching = (9q – q) / 2 = 4q

    when C is touched with A

    charge on A and C each after touching

    = 4q + 0 / 2 = 2q

    When C is touched with B

    charge on each of them

    (2q + 4q ) / 2 = 3 q

    Final charge on C = 3q
