In the future people will only enjoy one sport: Electrodisc. In this sport you gain points when you cause metallic discs hovering on a field to exchange charge. You are an Electrodisc player playing the popular four disc variant. The disks have charges of qA = -8.0 μC, B = -2.0 μC, qc = +5.0 μC, and qp = +12.0 μC. (a) You bring two disks together and then separate them. You measure the resulting charge of these two disks and find that it is +5.0 µC per disk. Which two disks did you bring together? O A and B O A and C O A and D O B and C OB and D O C and D (b) You bring three disks together and then separate them. You measure the resulting charge of these three disks and find that it is +3.0 µC per disk. Which three disks did you bring together? O A, B, and C O A, B, and D O A, C, and D O B, and D (c) Given the resulting charge of each disk measured in (b) is +3.0 μC, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
