Initial angular velocity of a circular disc of mass `M` is `omega_(1)`. Then two small spheres of mass `m` are attached gently to two diametrically opposite points on the edge of the disc. What is the final angular velocity of the disc -

Options

A. `((M+m)/(M))omega_(1)`
B. `((M+m)/(m))omega_(1)`
C. `((M)/(M+4m))omega_(1)`
D. `((M)/(M+2m))omega_(1)`

Answer

C
