A) \[4s\]
B) 0.5s
C) \[2s\]
D) 0.25 s
Correct Answer: C
Solution :
We know that, \[T=2\pi \sqrt{\frac{I}{MB}}\] \[T=2s,\] \[I=\frac{I}{2}\] \[M=\frac{M}{2}\] \[\therefore \] \[T=2\pi \sqrt{\frac{I}{MB}}\] \[\Rightarrow \] \[\frac{T}{T}=\sqrt{\frac{I}{I}\times \frac{M}{M}}=1\] \[\Rightarrow \] \[T=T\] \[\Rightarrow \] \[T=2\,s\]You need to login to perform this action.
