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

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 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:

If a bar magnet of magnetic moment M is kept in a uniform magnetic field B, its time period of oscillation is T. In the same magnetic field, the time period of another magnet of same dimension and same mass but of moment M/4 is.

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 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:

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:

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?
