Rank the following five capacitors from largest to smallest according to the potential difference between the plates.
   (a) a 20-F capacitor with a 4-V potential difference between its plates
   (b) a 30-F capacitor with charges of magnitude 90 C on each plate
   (c) a capacitor with charges of magnitude 80 C on its plates, differing by 2 V in potential,
   (d) a 10-F capacitor storing energy 125 J
   (e) a capacitor storing energy 250 J with a 10-V potential difference

  1.e > a > b > d > c
  2.e > d > a > b > c
  3.c > b > a > d > e
  4.b > a = c > d = e

Question 2

Two charged objects attract one another with a force F. If the charge on both objects is doubled and the distance between them is also doubled, what will be the force between them?
