A) 12
B) 6
C) 1.5
D) 0.75
Correct Answer: C
Solution :
\[T=2\pi \sqrt{\frac{I}{MB}}\] Or \[T\propto \frac{1}{\sqrt{B}}\] or \[\frac{{{T}_{2}}}{{{T}_{1}}}=\sqrt{\frac{{{B}_{1}}}{{{B}_{2}}}}\] Or \[\frac{{{T}_{2}}}{3}=\sqrt{\frac{1}{4}}\] Or \[{{T}_{2}}=1.5\,s\]You need to login to perform this action.
