.

figure
1 of 1
the figure shows the potential energy of a particle moving along the x-axis. the energy is measured in joules. there is a linear vertical potential barrier at x equal to 1 meter. for x from 1 to 4 meters the energy linearly increases from 2 to 8 joules. for x from 4 to 6 meters the energy linearly decreases to 0. for x from 6 to 8 meters the energy linearly increases to 12 joules and keeps growing for further distances.

part a
where are the particle's turning points?

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
