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
