Physics - Geometrical Optics Question with Solution | TestHub

When the gap between two identical concave thin lenses$\left(\mu =\frac{3}{2},f=10 \mathrm{cm}\right)$placed in contact is filled with certain liquid, the image of an object placed at$15 \mathrm{cm}$from lens combination shifts away from the lens by$\raisebox{1ex}{$5$}\!\left/ \!\raisebox{-1ex}{$4$}\right. \mathrm{cm}$. If the refractive index of the liquid is$\mu$, then write$3\mu$as your answer.
