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 center of a uniform circular disc of radius `r` and mass `M_(2)` so that both are coplanar. The center of mass of the combination from the center of the disc is (Assume that the point of attachment is at the origin)
1) `L``(``M_(1)``+``M_(2)``)``//``2``M_(1)`
2) `L``M_(1)``//``2``(``M_(1)``+``M_(2)``)`
3) `2``(``M_(1)``+``M_(2)``)``//``L``M_(1)`
4) `2``L``M_(1)``//``(``M_(1)``+``M_(2)``)``
