A) \[\frac{1}{n}\]
B) \[n\]
C) \[{{n}^{2}}\]
D) \[\frac{1}{{{n}^{2}}}\]
Correct Answer: D
Solution :
For minimum resultant, the n resistors are connected in parallel\[T=2\pi \,\sqrt{\frac{L}{g}}\] For maximum resultant, the n resistors are connected in series,\[\frac{L}{2}\] \[\Rightarrow \] \[T=2\pi \sqrt{\frac{L}{2g}}\]
