Question

A cylindrical plastic bottle of negligible mass is filled with 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 . If the radius of the bottle is 2.5 cm then  is close to: (density fo water = $\left.10^3 \mathrm{~kg} / \mathrm{m}^3\right)$

Select the correct option:

A

$2.50 \mathrm{rad} \mathrm{s}^{-1}$

B

$3.75 \mathrm{rad} \mathrm{s}^{-1}$

C

$5.00 \mathrm{rad} \mathrm{s}^{-1}$

D

$1.25 \mathrm{rad} \mathrm{s}^{-1}$
