A compound sphere is made by joining a hemispherical shell and a solid hemisphere of same radius `R` and same mass as shown in figure. This system is kept between two smooth parallel walls and a smooth floor with the hollow hemisphere on the top as shown in figure. The maximum angular velocity of the compound shere when the system is slightly disturbed is `(` all surfaces are smooth `)`
