A particle at the end of a spring executes simple harmonic motion with a period t1 , while the corresponding period for another spring is t2 . If the period of oscillation with the two springs in series is T, then

  • Option 1)

    T=t_{1}+t_{2}\; \; \;

  • Option 2)

    T^{2}=t_{1}^{2}+t_{2}^{2}\; \;\; \;

  • Option 3)

    T^{-1}=t_{1}^{-1}+t_{2}^{-1}\; \; \; \;

  • Option 4)

    T^{-2}=t_{1}^{-2}+t_{2}^{-2}
