A container contains two immiscible liquids p1 and p2 (> p1). A capillary tube of radius r is inserted in the liquid so that its bottom reaches upto denser liquid.the denser liquid rises in the capillary and attains a height h from the interface of the liquid, which is equal to be column length of lighter liquid. Assuming angle of contact to be zero the surface tension of heavier liquid is
