A uniform rod is suspended horizontally from its mid-point. A piece of metal whose weight is $w$ is suspended at a distance $l$ from the mid-point. Another weight $W_1$ is suspended on the other side at a distance $l_1$ from the mid-point to bring the rod to a horizontal position. Wben $w$ is completely immersed in water, $w_1$ needs to be kept at a distance $l_2$ from the mid-point to get the rod back into horizontal position. The specific gravity of the metal piece is
