The size of the image of an object, which is at infinity, as formed by a convex lens of focal length 30cm is 2 cm. If a concave lens of focal length 20 cm is placed between the convex lens and the image at a distance of 26 cm from the convex lens, calculate the new size of the image
- 1.25 cm
- 2.5 cm
- 1.05 cm
- 2 cm
Answer
(B) 2.5 cm
