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 is directly proportional to the density of the liquid
Correct option is C) 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.
