A parallel-plate capacitor has a capacitance of 440 pF, a plate area of 110 cm², and a mica dielectric ( = 5.40) completely filling the space between the plates. At 44.0 V potential difference, calculate (a) the electric field magnitude E in the mica, (b) the magnitude of the free charge on the plates, and (c) the magnitude of the induced surface charge on the mica.
