3. In the figure below, the radius of the capacitor plates is R = 18.0 cm, the peak emf of the voltage source is 220 V and it oscillates at w = 130 rad/s. The maximum value of the displacement current is 7.60 µA. a) What is the maximum value of dOE/dt, where DE is the electric flux through the region between the plates? b) What is the separation d between the plates? c) Find the maximum value of the magnitude of B between the plates at a distancer = 11.0 cm from the center.
