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

`T prop 1/sqrt(A)`

C

`T prop 1/prop`

D

`T prop 1/sqrt(m)`

Text Solution

Verified by Experts

The correct Answer is:
B
Restoring force=`Axrhog=kximpliesk=arhog
implies T=2pi sqrt(m)/(Arhog)`
