Q. If a liquid is placed in a vertical cylindrical vessel and the vessel is rotated about its axis, the liquid will take the shape of figure
A) [image:10_image60.emf]
B) [image:10_image61.emf]
C) [image:10_image62.emf]
D) [image:10_image63.emf]
Explanation
(c) For the given angular velocity of rotation, the centrifugal force $F \propto r$; therefore, more liquid will be accumulated near the wall of tube and the liquid meniscus will become concave upwards
