A 60 cm metal rod `M_(1)` is joined to another 100 cm metal rod `M_(2)` to form an L shaped single piece. This piece is hung on a peg at the joint. The two rods are observed to be equally inclined to the vertical. If the two rods are equally thick, the ratio of density of `M_(1)` to that of `M_(2)` is
