Question
A cylinder is floating in a liquid with 20cm of its length immersed in liquid of density 1.2gm/cc. Find the time period of oscillation when disturbed from mean position.
Solution
Time period of oscillation of cylinder floating in the liquid is given by,

where,
is the length of the cylinder inside the liquid.
Here,
= 20 cm.
Therefore time period of the oscillation is given by,

where,

Here,

Therefore time period of the oscillation is given by,
