3. A circular parallel plate capacitor of radius R = 1 cm is connected to a time-dependent voltage, V(t) = (10V) sin (wt), with a frequency of f = 100 Hz. The capacitance of the capacitor is constant at 2.0 uF. (a) Find the charge, q(t), on the capacitor. (b) Find the displacement current, Ia, inside of the capacitor. (c) Find the electric field, E(t), inside of the capacitor. (d) Find the magnetic field, B(t), outside of the capacitor at a distance r from the capacitor's axis.
