Q. The time period of a freely suspended magnet is $2\ sec$. If it is broken in length into two equal parts and one parts is suspended in the same way, then its time period will be
A) 4 $\sec$
B) 2 $\sec$
C) $\sqrt{2}\ sec$
D) 1 $\sec$
Explanation
(d) $T^{'} = \frac{T}{n} \Rightarrow T^{'} = \frac{2}{2} = 1sec$
