A vertical `U-tube` contains a liquid. The total length of the liquid column inside the tube is `1`. When the liquid is in equilibrium, the liquid surface in one of the arms of the `U-tube` is pushed down slightly and released. The entire liquid column will undergo a periodic motion.

A

The motion is not simple harmonic motion.

B

The motion is simple harmonic motion.

C

If it undergoes simple harmonic motion, the time period will be `2pisqrt(l//g)`.

D

If it undergoes simple harmonic motion, the time period will be `2pisqrt(l//2g)`.
