Question
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, 9B = -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, C, 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?
