A pendulum is hanging from the ceiling of a cage . If the cage moves up with constant accelration 'a' the tension is `T_(1)`. If it moves down with the same acceleration 'a' then tension is `T_(2)`. If the cage moves horizontally with the same accelration 'a', then the tension is T in equilibrium w.r.t. cage. Then `2T^(2)` is

A

`T_(1)^(2)+T_(2)^(2)`

B

`(T_(1)+T_(2))^(2)`

C

`2T_(1)T_(2)`

D

`4T_(1)T_(2)`
