Chapter 4: Q7E (page 809)
A parallel-plate air capacitor is to store charge of magnitude on each plate when the potential difference between the plates is . (a) If the area of each plate is , what is the separation between the plates? (b) If the separation between the two plates is double the value calculated in part (a), what potential difference is required for the capacitor to store charge of magnitude on each plate?
Short Answer
The separated distance is
The potential difference of 84V required for the capacitor to store the charge
