A particle at the end of the spring executes S.H.M with a period t_1, while the corresponding period for another spring is t_2. If the period of oscillation will two springs in series is 'T', then (same particle connected in all the cases)

A particle at the end of the spring executes S.H.M with a period t_1,

1.	A particle at the end of the spring executes S.H.M with a period t_1, while the corresponding period for another spring is t_2. If the period of oscillation will two springs in series is 'T', then (same particle connected in all the cases)
Answer» `T = T-1 + t_2` `T^2 = t_1^2 + t_2^2` `T^2 = t_1^2 + t_2^2` `T^(-2) = t_(1)^(-2) + t_2^(-2)` ANSWER :B
