• question_answer1) A particle at the end of a spring executes simple harmonic motion with a period\[{{t}_{1}},\]while the corresponding period for another spring is\[{{t}_{2}}\]. If the period of oscillation with the two springs in series is T, then
  A)
   \[T={{t}_{1}}+{{t}_{2}}\]              
  done clear
  B)
         \[{{T}^{2}}=t_{1}^{2}+t_{2}^{2}\]            
  done clear
  C)
         \[{{T}^{-1}}=t_{1}^{-1}+t_{2}^{-1}\]
  done clear
  D)
         \[{{T}^{-2}}\,=t_{1}^{-2}+t_{2}^{-2}\]
