One end of a thin uniform rod of length ...

One end of a thin uniform rod of length L and mass `M_(1)` is rivetted to the centre of a uniform circular disc of radius 'r' and mass `M_(2)` so that that both are coplanar. The centre of mass of the combination from the centre of the disc is (Assume that the point of attachment is at the origin).

A

`(L(M_(1)+M_(2)))/(2M_(1))`

B

`(LM_(1))/(2(M_(1)+M_(2)))`

C

`(2(M_(1)+M_(2)))/(LM_(1))`

D

`(2LM_(1))/((M_(1)+M_(2)))`
