A wire is suspended vertically from a rigid support. When loaded with a steel weight in air, the wire extends by \( 16 \mathrm{~cm} \). When the weight is completely immersed in water, the extension is reduced to \( 14 \mathrm{~cm} \). The relative density of the material of the weight is
(1) \( 2 \mathrm{~g} / \mathrm{cm}^{3} \)
(2) \( 6 \mathrm{~g} / \mathrm{cm}^{3} \)
(3) \( 8 \mathrm{~g} / \mathrm{cm}^{3} \)
(4) \( 16 \mathrm{~g} / \mathrm{cm}^{3} \)
