    A capillary tube when immersed vertically in water, the rise of water column is up to height h1h_{1} on earth's surface. When this arrangement is taken into a mine of depth 'd', below earth's surface, the height of the water column is h2h_{2}. If RR is the radius of the earth, the ratio h2h1\frac{h_{2}}{h_{1}} is
