Two mirrors M₁ and M₂ having radii of curvatures R₁ = 20cm and R₂ = 30cm respectively if an object is placed at a distance 15 cm from both mirrors as shown. Then we obtain maximum magnification in

$$\begin{gathered} \text{ Here, }{\mathrm{f}}_1=10\mathrm{cm},{\mathrm{f}}_2=15\mathrm{cm} \\ \mathrm{u}=-15 \end{gathered}$$
for both mirrors in first mirror case object is between F and C gives  enlarged image. But in second case object is placed at F which gives Highly enlarged image. Hence maximum
magnification is produced is M₂.
