The height of the cylinder is 2 centimeters. The inner layer of the cylinder is labeled with permittivity, epsilon sub 1 and radius, r sub 1 equals 2 millimeters. The middle layer of the cylinder is labeled with permittivity, epsilon sub 2 and radius, r sub 2 equals 4 millimeters. The outer layer of the cylinder is labeled with permittivity, epsilon sub 3 and radius, r sub 3 equals 8 millimeters. A text below the cylinder reads epsilon sub 1 equals 8 epsilon sub 0, epsilon sub 2 equals 4 epsilon sub 0 and epsilon sub 3 equals 2 epsilon sub 0.
