A) \[2\pi \sqrt{\frac{m}{3K}}\]
B) \[2\pi \sqrt{\frac{3m}{2K}}\]
C) \[2\pi \sqrt{\frac{3m}{3K}}\]
D) \[2\pi \sqrt{\frac{3K}{m}}\]
Correct Answer: B
Solution :
For the system of springs, \[{{K}_{eq}}=\frac{K\times 2K}{K+2K}=\frac{2}{3}K\] \[T=2\pi \sqrt{\frac{m}{\frac{2}{3}K}}\] \[=2\pi \sqrt{\frac{3m}{2K}}\]You need to login to perform this action.
