Q111 / 180 · AIIMS 2015 · Physics

Motion of an oscillating liquid in a $U$ tube is

  • A
    periodic but not simple harmonic.
  • B
    non-periodic.
  • Correct answer
    C
    simple harmonic and time period is independent of the density of the liquid.
  • D
    simple harmonic and time period is directly proportional to the density of the liquid.

Solution

Motion of an oscillating liquid column in a $\mathrm{U}$ tube is SHM with period, $T=2 \pi \sqrt{\frac{h}{g}}$, 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.

Hence, the correct answer is option: 'C'.
