Question
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 ω then
Options
A.water levels in both section A and B go up
B.water lavel in section A goes up and in B comes dowm
C.water level in section A comes down and that in B it goes up
D.water levels remain same in both sections
Solution
Water level in both A and B will go up. The pressure different thus created will provide the necessary centripetal force for the water body to rotate around the vertical axis.
