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 sqrt(rho)`
B. `Tprop rho^(0)`
C. `Tprop (1)/(rho)`
D. `T prop (1)/(sqrt(rho))`

Answer 1

Correct Answer - B
(b) `T=2pisqrt((l)/(g))`, where l is immersed length.
