Question-1 

Two bar magnets having same geometry with magnetic moment M and 2 M, are firstly placed in such a way that their similar poles are on the same side, then its period of oscillation is T1. Now the polarity of one of the magnets is reversed the time period of oscillations becomes T2. Then


(A)

T1 < T2


(B)

T1 > T2

(C)

T1 = T2

(D)
