  QUESTION: 1
  
  Solution:
  QUESTION: 2
  
  Solution:
  QUESTION: 3
  
  ### Hook's law holds good up to
  
  Solution:
  
  Hooke's law states that : The Force applied to an elastic material is directly proportional to the extension produced.
  
  We can write this as :
  
  F = ke
  
  Where k is the spring constant, F the force and e the extension.
  
  For Hooke's law to hold the extension and Force must always proportional.
  
  If the proportionality is broken then Hooke's law becomes invalid.
  
  Therefore Hooke's law holds good up to limit of proportionality.
