Problem

A solid piece of metal weighs

2.5\,\text{N}

in air. When it is completely immersed in water within a measuring cylinder, the water level rises from

200\,\text{mL}

230\,\text{mL}

. Taking

g = 10\,\text{m}\,\text{s}^{-2}

, find the density of the metal in

\text{kg}\,\text{m}^{-3}

. a)

2.5\times10^{3}\,\text{kg}\,\text{m}^{-3}

8.3\times10^{2}\,\text{kg}\,\text{m}^{-3}

8.3\times10^{3}\,\text{kg}\,\text{m}^{-3}

8.3\times10^{4}\,\text{kg}\,\text{m}^{-3}
