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 $\omega$ they
1 water levels in both section A and B go up
2 water level in section A goes up and that in B comes down
3 water level in section A comes down and that in B it goes up
4 water levels remain same in both sections
Explanation:
A Water level in both A and B will go up. The pressure difference thus, created will provided the necessary centripetal force for the water body to rotate around the vertical axis.
