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 montion angular frequency `omega`. If the radius of the bottle is 2.5 cm then `omega` is close to: (density of water `= 10^(3) kg//m^(3)`)

Options

A. `3.75 rad s^(-1)`
B. `1.25rad s^(-1)`
C. `2.50rad s^(-1)`
D. `5.00rad s^(-1)`

Answer

None

Explanation

`F_(res)=xApg`, `a=-(Axpg)/m =(Ag)/(v)x`, `omegasqrt((Ag)/(v))=rsqrt((pig)/(v))=2.5sqrt(10)=7.8`
