A) \[2\pi {{\left( \frac{M}{2k} \right)}^{1/2}}\]
B) \[2\pi {{\left( \frac{2M}{k} \right)}^{1/2}}\]
C) \[2\pi \frac{Mg\,\sin \,\text{ }\!\!\theta\!\!\text{ }}{2k}\]
D) \[2\pi {{\left( \frac{2Mg}{k} \right)}^{1/2}}\]
Correct Answer: A
Solution :
Time period, \[T=2\pi \sqrt{\frac{M}{k+k}}\] \[=2\pi \sqrt{\frac{M}{2k}}\]You need to login to perform this action.
