A hemi-spherical bowl of radius R=0.1 m is rotating about its own axis (vertical) with uniform angular speed ′ω′. A particle of mass 10−2 kg is placed on the inner surface (smooth) of the bowl at a height h′ from the bottom of bowl. What is the minimum value of ′ω′ to have a non-zero value of ′h′, for which the particle remains at rest?
