The charge on the square plates of a parallel-plate capacitor is Q.
 
  The potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. The amount of charge on the plates is now equal to A) 4Q.
  B) 2Q.
  C) Q.
  D) Q/2.
  E) Q/4.

Question 2
