Four identical metal spheres initially have the following charges on them: QA = -6 µC, QB = +3 µC, Qc = -4 μC, and QD = +7 μC. Spheres A and C are brought into contact which each other. After a short time, the spheres are separated again. Spheres B and D are brought into contact which each other. After a short time, the spheres are separated again. Finally Spheres A and B are brought into contact which each other. After a short time, the spheres are separated again. What is the final charge on each sphere? Select one: a. QA = -5 μC, QB = +5 μC, Qc = 0 μC, and Qp = 0 μC b. QA = 0 μC, QB = 0 μC, Qc = -5 µC, and Qp = +5 µC c. QA = 0 μC, QB = 0 μC, Qc = 0 μC, and Qp = 0 μC d. QA = -5 μC, QB = +5 μC, Qc = -5 μC, and Qp = +5 µC
