A) \[f\]
B) \[2f\]
C) \[\sqrt{2}f\]
D) \[\frac{1}{\sqrt{2}}f\]
E) None of these
Correct Answer: D
Solution :
For the given figure, \[f=\frac{1}{2\pi }\sqrt{\frac{{{k}_{eq}}}{m}}\] ?(i) \[=\frac{1}{2\pi }\sqrt{\frac{2k}{m}}\] If one spnng is removed, then\[{{k}_{eq}}=k\]and \[f=\frac{1}{2\pi }\sqrt{\frac{k}{m}}\] ?(ii) From Eqs. (i) and (ii), we get \[\frac{f}{f}=\sqrt{2}\] \[f=\frac{1}{\sqrt{2}}f\]You need to login to perform this action.
