A vertical separator partition is hinged at the base. If oil of unit weight 9 kN/m3 is stored to a height of h1 m on one side and the height of water stored on other side is h2 m that maintains the separator in a vertical position, then the ratio of h1 to h2 will be:
1
1 ∶ 3
2
\(\sqrt[3]{9}\) ∶ \(\sqrt[3]{10}\)
3
\(\sqrt[3]{100}\) ∶ \(\sqrt[3]{81}\)
4
\(\sqrt[3]{10}\) ∶ \(\sqrt[3]{9}\)
