Water rises up to height ' $x$ ' in a capillary tube immersed vertically in water. When the whole arrangement is taken to a depth ' $d$ ' in a mine, the water level rises up to height Y . If R is the radius of the earth then the ratio $\mathrm{Y}: \mathrm{x}$ is

$\quad \mathrm{R}:(\mathrm{R}+\mathrm{d})$

$\mathrm{R}:(\mathrm{R}-\mathrm{d})$

$\mathrm{R}:(\mathrm{R}-\mathrm{d})^2$

$\mathrm{R}:(\mathrm{R}+\mathrm{d})^2$
