A short bar magnet placed at a certain distance from a deflection magnetometer in tan A position produces a deflection of `60^@`. The magnet is now cut into three equal pieces. If one piece is kept at the same distance in tan A position from the deflection magnetometer, then the deflection produced is:

A

`30^@`

B

`60^@ xx(3)^(1/3)`

C

`60^@ xx(3)^(2/3)`

D

`60^@ xx(3)^(3/3)`
