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

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

B

`T=T_0 cos theta `

C

`T=(T)/( cos theta)`

D

` T^2 = (T_(0) ^(2))/( cos theta )`
