Motion of an oscillating liquid in a U tube is

Options

  1. Aperiodic but not simple harmonic.
  2. Bnon-periodic.
  3. Csimple harmonic and time period is independent of the density of the liquid.
  4. Dsimple harmonic and time period is directly proportional to the density of the liquid.

Correct answer

C. simple harmonic and time period is independent of the density of the liquid.

Step-by-step solution

Motion of an oscillating liquid column in a U tube is SHM with period, T=2 h g , where h is the height of liquid column in one arm of U tube in equilibrium position of liquid. Therefore, T is independent of density of liquid.
