Initial angular velocity of a circular disc of mass $$M$$ is $${\omega _1}.$$ Then two small spheres of mass $$m$$ are attached gently to diametrically opposite points on the edge of the disc. What is the final angular velocity of the disc?
A
$$\left( {{{M + m} \over M}} \right)\,\,{\omega _1}$$
B
$$\left( {{{M + m} \over m}} \right)\,\,{\omega _1}$$
C
$$\left( {{M \over {M + 4m}}} \right)\,\,{\omega _1}$$
D
$$\left( {{M \over {M + 2m}}} \right)\,\,{\omega _1}$$
