A disc of radius `R` has a light pole fixed perpendicular to the disc at its periphery whish in turn has a pendulum of legth `R` attached to its other end as shown in figure. The disc is rotated with a constant angular velocity `omega` The string is making an angle `45^(@)` with the rod. Then the angular velocity `omega` of disc is
