Examine the scenario.

a positively charged conductor is brought in contact with a negative conductor.

which choice most accurately describes the motion of charge between these two objects?

the protons in the positive object are attracted to the negatively charged object. some of the protons move from the positive object to the negative object.

the protons in the negative object are attracted to the positively charged object. some of the protons move from the negative object to the positive object.

the electrons in the negative object are attracted to the positively charged object. some of the electrons move from the negative object to the positive object.

the electrons in the positive object are attracted to the negatively charged object. some of the electrons move from the positive object to the negative object.

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, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) 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? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) 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? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) 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
