An iron cylinder 5 cm high was suspended in a vertical position on a spring and partially immersed in water. What is the cyclic frequency of small vertical oscillations of such a cylinder, if before immersion in water the cyclic frequency of oscillations on the spring was 12 rad/s? Ignore friction. The density of iron is 8000 kg/m3, g = 10 m/s2.
