A vibrations magnetometer consists of two indentical bar magnet placed one over the other that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is `2^(5//4)` s. One of the magnets is removed and if the other magnet oscillates in the same field, then the time period in second is :

Options

A. `2^(1//4)`
B. `2^(1//2)`
C. 2
D. `2^(3//4)`
