In a long glass tube, mixture of two liquids A and B with refractive indices $\displaystyle 1.3$ and $\displaystyle 1.4$ respectively, forms a convex refractive meniscus towards A. If an object placed at $\displaystyle 13$ cm from the vertex of the meniscus in A forms an image with a magnification of ' $\displaystyle -2^{\prime}$ then the radius of curvature of meniscus is :
