1.	A sphere has a concentric spherical cavity. The specific gravity of the material of the sphere is 8. the sphere is place on a surface of water. If in the equilibrium position the sphere just sinks in water, the ratio of theradius of cavity to the outer radius of the sphere is
Answer» SOLUTION :`((7)/(8))^(1//3)`
