142981 Liquid $A$ rises to a height of $10 \mathrm{~cm}$ in a capillary tube and liquid $B$ falls to a depth of 2 $\mathrm{cm}$ in the same tube. The density of $A$ and $B$ are $1 \mathrm{~g} / \mathrm{cm}^{3}$ and $10 \mathrm{~g} / \mathrm{cm}^{3}$ respectively. The contact angle of $A$ and $B$ with the tube is $0^{\circ}$ and $135^{\circ}$ respectively. If the surface tension of $A$ and $B$ are $S_{A}$ and $S_{B}$ then the ratio $\frac{S_{B}}{S_{A}}$ is:
