Problem

A solid sphere floats at the boundary between an upper layer of oil (

\rho=800\,\text{kg}\,\text{m}^{-3}

) and a lower layer of water (

\rho=1000\,\text{kg}\,\text{m}^{-3}

). Half of the sphere’s volume is in the oil and half is in the water. What is the density of the sphere? (a)

1000\,\text{kg}\,\text{m}^{-3}

(b)

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

(c)

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

(d)

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