Question

Motion of an oscillating liquid column in a U-tube is ?

• A. Periodic but not simple harmonic
• B. Non-periodic
• C. Simple harmonic and time period is independent of the density of the liquid
• D. Simple harmonic and time period depends on the density of the liquid.

Answer 1

Answer:

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

Motion of an oscillating liquid column in a U tube is SHM with period, T=2πgh​​, 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.
