A magnetic needle is made to vibrate in uniform field `H`, then its time period is `T`. If it vibrates in the field of intensity `4H`, its time period will be

Define the term time period of vibration.

A bar magnet is oscillating in the earth's magnetic field with a time period T . If the mass is increased four times, then its time period will be:

A bar magnet suspended freely in a uniform magnetic field is vibrating with a time period of 3s. If the field strength is increased to 4 times of the earlier field strength, then the time period (in second) will be

A bar magnet is oscillating in the earth's magnetic field with a time period T . If the mass is quadrupled, then its time period will be:

Time period in vibration magnetometer will be infinity at

A bar magnet suspended freely in uniform magnetic field is vibrating with a time period of 3 seconds. If the initial field strength is 2T . Then the final field strength, for which time period becomes 4 seconds is

An object is vibrating at 50 hertz. What is its time period?
