Two bar magnets having geometry with magnetic moments $M$ and $2 M$ are first placed in such a way that their similar poles are same side then its time period of oscillation is $T_{1}$ . Now the polarity of one of the magnet is reversed then the time period of oscillation is $T_{2}$ , so:NEET 2002

Options:

Answer:

Solution:

We can write $T = 2 π \frac{1}{MB} \Rightarrow T \propto \frac{1}{M}$ Case I : $M_{1} = 2 M + M$ Case II : $M_{2} = 2 M - M$ $∴ \frac{T _{1}}{T _{2}} = \frac{M}{3 M} = \frac{1}{3} \Rightarrow T_{2} = 3 T_{1}$
