142975 A uniform capillary tube of length $l$ and inner radius $r$ with its upper end sealed is submerged vertically into water. The outside pressure is $\mathbf{p}_{0}$ and surface tension of water is $\gamma$. When a length $x$ of the capillary is submerged into water, it is found that water levels inside and outside the capillary coincide. The value of $x$ is
142977 Liquid rises to a height of $2 \mathrm{~cm}$ in a capillary tube and the angle of contact between the solid and the liquid is zero. If the tube is depressed more now so that top of capillary is only $1 \mathrm{~cm}$ above the liquid, then apparent angle of contact between the solid and the liquid is
