Given a thin convex lens (refractive index u2), kept in a liquid (refractive index u1 u1 < u2

Given a thin convex lens refractive index μ2, kept in a liquid (refractive index μ1, μ1 < μ2) havin gradii of curvature |R1| and |R2|. Its second surface is silver polished. Where should an object be placed on the optic axis so that a real and inverted image is formed at the same place ?
