Question

A rectangular block of mass m and area of cross-section A floats in a liquid of density `rho`. If it is given a small vertical displacement from equilibrium, it undergoes oscillation with a time period T. Then
A. `T prop m`
B. `T prop rho`
C. `T prop (1)/(A)`
D. `T prop sqrt((1)/(rho))`

Answer 1

Correct Answer - D
(d) `T=2pisqrt((m)/(rhoAg))implies T prop (1)/(sqrt(rho))`
