Physics - Geometrical Optics Question with Solution | TestHub

A concave mirror of focal length$20 \mathrm{cm}$and a convex lens of focal length$10 \mathrm{cm}$are kept with their optic axes parallel but separated by$0.5 \mathrm{cm}$as shown in the figure. The distance between the lens and mirror is$10 \mathrm{cm}$. An object of height$3 \mathrm{mm}$is placed on the optic axis of lens at a distance$15 \mathrm{cm}$from the lens. Find the length of the image formed by the mirror in$\mathrm{mm}$.
