A rectangular block of mass m and area of cross-section A floats in a liquid of density . If it is given a small vertical displacement from equilibrium it undergoes with a time period T , Then:

Options

  1. AT 1 m
  2. BT A
  3. CT 1 A
  4. DT 1

Correct answer

C. T 1 A

Step-by-step solution

Restoring force =A g=k x array ll & K=A g & T=2 m A g array This shows that T 1 A .
