Problem

A solid piece of metal weighs 2.5 N2.5\,\text{N} in air. When it is completely immersed in water within a measuring cylinder, the water level rises from 200 mL200\,\text{mL} to 230 mL230\,\text{mL}. Taking g=10 m s−2g = 10\,\text{m}\,\text{s}^{-2}, find the density of the metal in kg m−3\text{kg}\,\text{m}^{-3}. (a) 2.5×103 kg m−32.5\times10^{3}\,\text{kg}\,\text{m}^{-3} (b) 8.3×102 kg m−38.3\times10^{2}\,\text{kg}\,\text{m}^{-3} (c) 8.3×103 kg m−38.3\times10^{3}\,\text{kg}\,\text{m}^{-3} (d) 8.3×104 kg m−38.3\times10^{4}\,\text{kg}\,\text{m}^{-3}
