A cylinderical wooden block of cross-section 15.0 `cm^(2)` and 250 gram attached to its bottom. The cylinder floats vertically. From the state of equilibrium, it is slightly depressed and released. If the specific gravity of wood is 0.3 and `g=9.8 ms^(-2)`, deduce the frequency of oscillation of the block.

Text Solution

Verified by Experts

Here, `(250+30)980=15.0xxlxxlxx980`
or `l=56//3 cm.`
Use the relation `T=2pisqrt(l//g)` and put the values.
