A deflection magnetometer is adjusted in the usual way . When a magnet is introduced , the deflection observed is `theta = 60^(@)` and the period of oscillation of the needle in magnetometer is T . When the magnet is removed the time period of oscillation is `T_(0)` . The relation between T and `T_(0)` is

A

`2 T^(2) = T_(0)^(2)`

B

`(2T^(2))/(sqrt3) = T_(0)^(2)`

C

`T = T_(0)`

D

`T^(2) = (T_(0)^(2))/(sqrt2)`
