A capacitor with parallel circular plates of radius R is discharging via a current of 11.0 A. Consider a loop of radius R/6 that is centered on the central axis between the plates.
(a) How much displacement current is encircled by the loop?
(b) The maximum induced magnetic field has a magnitude of 48 mT. At what radial distance from the central axis of the plate is the magnitude of the induced magnetic field 12.00 mT? (enter as a fraction of R)
