A long magnet is cut into two equal parts, such that the length of each half is same as that of original magnet. If the period of original magnet is $T$, the period of new magnet is

The time period of a freely suspended bar magnet in a field is $2\, \sec$. It is cut into two equal parts along its axis, (hen the time period is

A bar magnet is held at right angles to a uniform magnetic field. The couple acting on the magnet is to be halved by rotating it from this position. The angle of rotation is
