A 50-kg air conditioner is placed on top of a concrete pad that is 20 cm thick and has a cross-sectional area of 3.0 m2. What is the change in thickness of the pad caused by the air conditioner? Young's modulus for concrete is 2.3  1010 N/m2.
 
  A) 1.4  10-9 m
  B) 2.8  10-9 m
  C) 1.4  10-8 m
  D) 1.4  10-7 m
  E) 2.8  10-8 m
