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

Question 2

How does the range of an exchange force depend on the mass of the exchange particle?
 
  A) The range is longer for a massive exchange particle than for a light exchange particle.
  B) The range is shorter for a massive exchange particle than for a light exchange particle.
  C) The range does not depend on the mass of the exchange particle.
