A charge Q is uniformly spread over one surface of a very large nonconducting square elastic sheet having sides of length d.
 
  At a point P that is 1.25 cm outside the sheet, the magnitude of the electric field due to the sheet is E. If the sheet is now stretched so that its sides have length 2d, what is the magnitude of the electric field at P?
  A) 4E
  B) 2E
  C) E
  D) E/2
  E) E/4
