Capacitors

You have a parallel-plate capacitor. (a) Determine the average field between the plates if a 120-V potential difference exists across the plates. Their separation is 0.50 cm. (b) A spark will jump if the magnitude of the field exceeds 3.0 x 10⁶ V/m when air separates the plates. What is the closest the plates can be placed to each other without sparking?
