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)`)

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 in starts performing simple harmonic motion at angular frequency omega . If the radius of the bottle is 2.5 cm then omega is close

A cylindrical object of outer diameter 20 cm and mass 2 kg floats in water with its axis vertical. If it is slightly depressed and then released, find the time period of the resulting simple harmonic motion of the object.

A 0.1 kg mass is suspended from a wire of negligible mass. The length of the wire is 1 m and its cross sectional area is 4.9 times 10^-7 m^2 . IF the mass is pulled a little in the vertically downward direction and released, it performs simple harmonic motion of angular frequency 140 rad.s^-1 . IF the young's modulus of the material of the wire is n times 10^9 N.m^-2 . Find the value of n.

A cubical wood piece of mass 13.5 gm and volume 0.0027 m^3 float in water. It is depressed and released, then it executes simple harmonic motion. Calculate the period of oscillation ?

A wooden cube floating in water supports a mass 0.2 kg on its top. When the mass is removed the cube rises by 2cm. What is the side legnth of the cube ? Density of water = 10^3 kg//m^3
