The period of oscillation of a magnet at a place is `4`seconds. When it is remagnetised, so that the pole strength becomes `1//9th` of initial value, the period of oscillation in seconds is

The period of oscillations of a magnet is 2 sec. When it is remagnetised so that the pole strength is 4 times its period will be

The period of oscillations of a magnet is 2 sec. When it is remagnetised so that the pole strength is 4 times its period will be

The period of oscillations of a magnet is 2 sec. When it is remagnetised so that the pole strength is 4 times its period will be

The period of oscillation of a magnet is T in earth's magnetic field. When another identical magnetic is kept over it with their like poles together, the new period of oscillation is

If the period of oscillation of mass M suspended. From a spring is one second, then the period of 4 M will be

The period of oscillation of a suspended thin cylindrical magnet is 4 seconds. It is broken into exactly two halves. Find the period of oscillation of each half when freely suspended.

The period of oscillation of a suspended thin cylindrical magnet is 4 seconds. It is broken into exactly two halves. Find the period of oscillation of each half when freely suspended.

If the period of oscillaion of freely suspended bar magnet in earth's horizontal field H is 4 sec. When another magnet is brought near it, the period of oscillation is reduced to 2s. The magnetic field of second bar magnet is
