a man is sitting on a chair. identify the true scenario from the following options: (5 points)
group of answer choices

the man exerts a greater downward force on the chair than the upward force exerted on him by the chair.

the chair exerts a greater upward force on the man than the downward force exerted on the chair by the man.

the chair exerts an upward force on the man, while the man does not exert any force on the chair.

the man exerts a downward force on the chair, while the chair does not exert any force on him.

the magnitude of the downward force exerted by the man on the chair is equal to that exerted on him by the chair.

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
