A wooden ball of density `sigma` is released from the bottom of a tank which is filled with a liquid of density `rho``(rho>sigma)`up to a height `h_(1)`. The ball rises in the liquid, emerges from its surface and attains a height `h_(2)` in air.If viscous effects are neglected,the ratio `h_(2)/h_(1)` is

`(rho/sigma+1)`

`(rho/sigma-1)`

`(rho/sigma)`

`(sigma/rho)`
