A hemispherical bowl of radius R is rotated about its axis of symmetry which is kept vertical. A small block is kept in the bowl at a position where the radius makes an angles with the vertical. The block rotates with the bowl without slipping. The friction coefficient between block and the bowl surface is . Find the range of angular speed for which the block will not slip.

can sum1 pls tell me y mR^2 is replaced with mR ?

from question, we see that here moment of inertia of hemisphere is mr^2 .it cancelled the radius of block which was inserted.
