Two parallel plates were separated by a distance of 0.50 mm with only vacuum in between. Both plates have a diameter of 10 cm. The initial magnitude of the charge on the capacitor is qo = 9.0 x 10-8C, and after discharge is initiated, the potential difference across the capacitor is decreasing at a rate of 300kV/s. (a) What is the displacement current in the capacitor? (b) What is the magnetic field strength on the axis? (c) What is the magnetic field strength 4.0 cm from the axis? (d) What is the magnetie field strength 6.0 cm from the axis? (e) What is the Poynting vector (show both magnitude and direction) 5.0 cm from the axis? (f) What is the power that crosses the closed cylindrical surface surrounding the space between the plates at the beginning of the discharging?
