A given shaped glass tube having uniform cross-section is filled with water and is mounted on a rotatable shaft as shown in figure. If the tube is rotated with a constant angular velocity `omega` then :

A

water levels in both sections `A` and `B` go up

B

water level in section `A` goes up and that in sectioon `B` comes down

C

water level in section `A` comes dowm andthat in `B` goes up

D

water level remains the same in both the sections

Text Solution

Verified by Experts

The correct Answer is:
A
When the tube is rotated with a constant angular velocity centrifugal force acting radially outwards towards `A = mL omega^(2)` and towards `B = m(2L)omega^(2)`. Therefore, water levels in both, section `A` and section `B` go up.
