A cylinder of radius R = 1 m and height H = 3 m two- thirds filled with water, is rotated about its vertical axis as shown in Fig. Determine the speed of rotation when a. the: water just starts spilling over the rim. b. the point at the centre of the base is just exposed.

A cylindrical vessel of radius R=1m and height H=3m is filled with an ideal liquid up to a height of h=2 m. the contaienr with liquid is rotated about its central vertical axis such that the liquid just rises to the brim. Calculate the angular speed (omega) of the container.
