A thin plano-convex lens of focal length 15 cm has its plane side silvered. An object is placed on the principal axis of the lens at a distance 20 cm from it as shown in the figure. The final position of the image is
\(20 \mathrm{~cm}\)
- 60 cm to the right of the lens
- 60 cm to the left of the lens
- 30 cm to the left of the lens
- 12 cm to the left of the lens
Answer
(D) 12 cm to the left of the lens
