Two balls of mass m(1) = 56g and m(2) = ...

Two balls of mass `m_(1) = 56g` and `m_(2) = 28g` are suspended on two threads of length `l_(1) = 7 cm` and `l_(2) = 11 cm` at the end of a freely hanging rod (Fig). Determine the angular velocity o at which the rod should be rotated about the vertical axle so that it remains in the vertical position.
