Problem

On the Moon the acceleration due to gravity is about

1.6\,\text{m}\,\text{s}^{-2}

. A rock sample shows a weight of

3.2\,\text{N}

on the Moon. If the sample occupies a volume of

200\,\text{cm}^3

, find its density. a)

1.6\times 10^{4}\,\text{kg}\,\text{m}^{-3}

1.6\times 10^{3}\,\text{kg}\,\text{m}^{-3}

1.0\times 10^{4}\,\text{kg}\,\text{m}^{-3}

2.56\times 10^{4}\,\text{kg}\,\text{m}^{-3}
