7. (15 points) In the figure, R = 1.00 kN, L = 0.25 mh, and an air-filled capacitor has parallel circular plates of radius 5.50 cm, separated by 4.50 mm. The generator provides an emf with voltage 240.0 V and frequency equal to the resonant frequency of the RLC circuit. (a) What is the wavelength of the electromagnetic wave emitted from the capacitor? (b) Att = 3.00 ms, what is the magnitude of the magnetic field within the capacitor, at radial distance 3.40 cm? (The electric field between the plates is uniform) ww R L 000
