A cylinder with diameter D, floats in a liquid as shown in the figure. When the cylinder is slightly offset with respect to its vertical axis, the cylinder will oscillate with a frequency w.

Determine, with the help of a dimensional analysis, how the frequency is related to these variables. If the mass of the cylinder increases, determine what happens with the frequency.
