A) \[T=2\pi \sqrt{\frac{m}{4k}}\]
B) \[T=2\pi \sqrt{\frac{m}{2k}}\]
C) \[T=2\pi \sqrt{\frac{m}{k}}\]
D) \[T=2\pi \sqrt{\frac{m}{8k}}\]
Correct Answer: C
Solution :
\[{{K}_{1}}\]and \[{{K}_{2}}\] are parallel and \[{{K}_{3}}\] and \[{{K}_{4}}\] are parallel. The two combinations are in series with each other \[{{k}_{1}}+{{k}_{2}}=2k\] \[{{k}_{3}}+{{k}_{4}}=4k\] \[\frac{1}{{{k}_{eq}}}=\frac{1}{2k}+\frac{1}{2k}\] \[{{k}_{eq}}=k\] \[T=2\pi \sqrt{\frac{m}{k}}\]
