A uniform spring has a centain block suspended from it and its period for vertical oscillation is `T_(1)`. The spring is now cut into two parts of lengths `(1)/(3) rd and (2)/(3) rd` of original length and these springs are connected to the same block as shown in the figure. If time period of oscillation now is `T_(2) " then " T_(1)//T_(2)`.

A

`sqrt((9)/(2))`

B

`1 : 1`

C

`1 : 3`

D
