A test tube of length l and area of cross-section A has some iron fillings of mass M. The test tube floats normally in a liquid of density `rho` with length x dipped in the liquid. A distribuing force makes the tube oscillate in the liquid. The time period of osciallation is given by (neglect the mass of the test tube)
