A) \[2:1\]
B) \[1:1\]
C) \[1:4\]
D) \[4:1\]
E) \[1:2\]
Correct Answer: E
Solution :
Time-period of spring mass system is \[T=2\pi \sqrt{\frac{m}{k}}\] When connected in series \[k=\frac{k}{2}\] When connected in parallel \[k\,=2k\] \[\therefore \] \[\frac{T}{T\,\,}=\sqrt{\frac{k}{2(2k)}}=\frac{1}{2}\]You need to login to perform this action.
