A mass `m` is suspended separately by two different spring of spring constant `K_(1)` and `k_(2)` given the time period `t_(1)` and`t_(2)` respectively if the same mass `m` is shown in the figure then time period `t` is given by the relation

Options

A. `t= t_(1) + t_(2)`
B. `t =(t_(1)t_(2))/(t_(1)+ t_(2))`
C. `t^(2) =t_(1)^(2)+t_(2)^(2)`
D. `t^(-2) =t_(1)^(-2)+t_(2)^(-2)`

Answer

D
