Question

What is the electric field Bboth magnitude and direction, at the midpoint between the two disks? Express your answer to two significant figures and include the appropriate units Two 10-cm-diameter charged disks face each other, 16 cm apart. The left disk is charged to -50 nC and the right disk is charged to+50 nC ETValue Units Submit Request Answer Part B O To the left disk OTo the right disk Parallel to the plane of the disks Submit Request Answer Part C What is the force F on a-1.7 nC charge placed at the midpoint? Express your answer to two significant figures and include the appropriate units F.1 Value Units Submit Part D O To the left disk To the right disk. Parallel to the plane of the disks.

Explanation / Answer

Part A)

E = left/20 + right/20

E = (q/A)/20 + (q/A)/20

E = (2q/A)/20

E = q/A0

E = (50*10^-9)/(3.14*0.05^2*8.85*10^-12)

|E| = 7.2*10^5 N/C

Part B)

E is directed from right disk to left disk

Part C)

F = q*E

F = 1.7*10^-9*7.2*10^5

F = 1.22*10^-3 N

Part D)

Force on the charge is directed towards right disk
