A light beam traveling horizontally enters a hole in the side of a laboratory on planet X.
 
  The laboratory is 40.0 m wide. If the light beam hits the far wall a distance 0.20 mm below the height it entered the laboratory, what is the acceleration of gravity on planet X?
  A)
 
  2.25  1010 m/s2
  B)
 
  8.00  106 m/s2
  C)
 
  9.81 m/s2
  D)
 
  4.50  105 m/s2
  E)
 
  3.75  103 m/s2
