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 = ā8.0 Āµc, qb = ā2.0 Āµc, qc = +5.0 Āµc, and qd = +12.0 Āµc. (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 Āµc 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 Āµc 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 Āµc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons

Two 2.0-cm-diameter disks face each other, 1.0 mm apart. they are charged to Ā±10 nc. what is the electric field strength between the disks? a proton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (Īµ0 = 8.85 Ć 10-12 c2/n Ā· m2)
