The time period of a vibration magnetometer is `T_(0)`. Its magnet is replaced by another magnet whose moment of inertia is 3 times and magnetic moment is `1//3` of the initial magnet. The time period now will

A magnet has time period of oscillations T in earth's magnetic field at a place. If it is replaced by a magnet of magnetic moment six times the magnetic moment of the original one, the time period at the same place will be

The time period of oscillation of a bar magnet suspended horizontaliy along the magnetic meridian is T_(0) . If this magnet is replaced by another magnet of the same size and pole strength but with double the mass, the new time period will be

The time period of oscillation of a bar magnet suspended horizontaliy along the magnetic meridian is T_(0) . If this magnet is replaced by another magnet of the same size and pole strength but with double the mass, the new time period will be

The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is T. The magnet is cut along its length into three parts and these parts are then placed together. The time period of this combination will be

The period of oscillation of a magnet in a vibration magnetometer is 8 seconds. The period of oscillation of magnet whose magnetic moment is four times that of the first magnet is :

The magnet of a vibration magnetometer is heated so as to reduce its magnetic moment by 19% . By doing this the period time of the magnetometer will

The magnet of a vibration magnetometer is heated so as to reduce its magnetic moment by 19% . By doing this the period time of the magnetometer will

The magnet of vibration magnetometer is heated so as to reduce its magnetic moment by 36%. By doing this the periodic time of the magnetometer will
