Acapacitor is connected to a resistor and an ac voltage source. the output of the source is given by 0- vo cos ear. at a point between the plates of the capacitor a) there is a time varying magnetic field induced by a time varying electric ficld. b) there is a constant magnetic field induced by a constant and uniform electric field. c) there is no magnetic field, because no current flows between the plates. d) there is a nonzero magnetic field due to ampere's law e) there is a nonzero magnetic field created by the charges moving in the space between the plates.
