142695 A vessel contains oil (density $=0.8 \mathrm{gm} / \mathrm{cm}^{3}$ ) over mercury (density $\left.=13.6 \mathrm{gm} / \mathrm{cm}^{3}\right)$. A homogeneous sphere floats with half of its volume immersed in mercury and the other half in oil. The density of the material of the sphere in $\mathrm{gm} / \mathrm{cm}^{3}$ is

142697 A steel wire is suspended vertically from a rigid support. When loaded with a weight in air, it extends by $l_{\mathrm{a}}$ and when the weight is immersed completely in water, the extension is reduced to $l_{\mathrm{w}}$. Then the relative density of material of the weight is

1 $l_{\mathrm{a}} / l_{\mathrm{w}}$
2 $\frac{l_{\mathrm{a}}}{l_{\mathrm{a}}-l_{\mathrm{w}}}$
3 $l_{\mathrm{w}} /\left(l_{\mathrm{a}}-l_{\mathrm{w}}\right)$
4 $l_{\mathrm{w}} / l_{\mathrm{a}}$
