As a parallel-plate capacitor with circular plates 20 cm in diameter is being charged, the current density

Question:

As a parallel-plate capacitor with circular plates 20 cm in diameter is being charged, the current density of the displacement current in the region between the plates is uniform and has a magnitude of 20A/m2?

(a) Calculate the magnitude B of the magnetic field at a distance r = 50 mm from the axis of symmetry of this region.

(b) Calculate d E/dt in this region.
