Problem

A container holds a

0.40\,\text{m}

layer of oil (density

800\,\text{kg}\!/\!\text{m}^3

) floating on top of a

0.60\,\text{m}

layer of water (density

1000\,\text{kg}\!/\!\text{m}^3

). The container is open to the atmosphere. What is the gauge pressure at the bottom of the container? (a)

5.9\times10^{3}\,\text{Pa}

(b)

3.1\times10^{3}\,\text{Pa}

(c)

9.0\times10^{3}\,\text{Pa}

(d)

7.8\times10^{3}\,\text{Pa}
