A thin circular ring of mass M and radius r is rotating about its axis with a constant angular velocity $$\omega $$. Four objects each of mass m, are kept gently to the opposite ends of two perpendicular diameters of the ring. The angular velocity of the ring will be :

$${{M\omega } \over {4m}}$$

$${{M\omega } \over {M + 4m}}$$

$${{\left( {M + 4m} \right)\omega } \over M}$$

$${{\left( {M - 4m} \right)\omega } \over {M + 4m}}$$
