A disc of radius (R) has a light pole fixed perpendicular to the disc at the circumference which in turn has a pendulum of length (R) attached to its other end as shown in fig. The disc is rotated with a constant angular velocity (`omega` ). The string is making an angle `30^(@)` with the rod. Then the angular velocity (`omega`) of
