Potential difference in a capacitor A capacitor consists of two large metal disks placed a distance s apart (see the figure). The radius R of each disk is 5.6 m, the gap s between the disks is 1.2 mm, and the thickness t of each disk is 0.5 mm. The disk on the left has a net charge of 3.6×10−4 C and the disk on the right has a net charge of −3.6×10−4 C. Calculate the potential difference V2 − V1, where location 1 is inside the left disk at its center, and location 2 is in the center of the air gap between the disks. Use ε0 = 8.85×10−12 C2/(N⋅m2). V2 − V1 = V Read more Read less
