Let `T_(1)` and `T_(2)` be the time periods of two springs A and B when a mass m is suspended from them separately. Now both the springs are connected in parallel and same mass m is suspended with them. Now let T be the time period in this position. Then

A

`(t_(1)t_(2))/(t_(1) + t_(2))`

B

`(t_(1) t_(2))/(sqrt(t_(1)^(2) + t_(2)^(2)))`

C

`sqrt((t_(1) t_(2))/(t_(1) + t_(2)))`

D

`t_(1) + t_(2)`
