Two plastic bowling balls, 1 and 2, are rubbed with cloth until they each carry a uniformly distributed charge of magnitude 0.60 nc . ball 1 is negatively charged, and ball 2 is positively charged. the balls are held apart by a 800-mm stick stuck through the holes so that it runs from the center of one ball to the center of the other. what is the magnitude of the dipole moment of the arrangement?

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 = β8.0 Β΅c, qb = β2.0 Β΅c, qc = +5.0 Β΅c, and qd = +12.0 Β΅c. (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 Β΅c 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 Β΅c 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 Β΅c, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
