A parallel-plate air capacitor is to store charge of magnitude 290pC on each plate when the potential difference between the plates is 36.0V
A: If the area of each plate is 6.80 cm2, 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 290 pC on each plate?
