A cylindrical plastic bottle of negligible mass is filled with $\displaystyle 310$ ml of water and left floating in a pond with still water. If pressed downward slightly and released, it starts performing simple harmonic motion at angular frequency $\displaystyle \omega$. If the radius of the bottle is $\displaystyle 2.5$ cm then $\displaystyle \omega$ is close to: (density of water $\displaystyle =10^3 \mathrm{~kg} / \mathrm{m}^3$ )
Official answer
No correct option: NTA dropped this question in its final answer key.
