To obtain an enlarged real inverted image beyond 2F2 after refraction by convex lens, where should the object be placed?

Correct option is B

To obtain an enlarged real inverted image beyond 2F2​ after refraction by a convex lens, where F2​ is the image focus and F1​ is the object focus, one need to place the object at a position such that the image is formed beyond 2F2​.
Here’s how it works:
1. If the object is at infinity: The image will be formed at F2​, and it will be highly diminished, not enlarged.
2. If the object is between F1 ​ and 2F1 ​: The image will be formed beyond 2F2​, and it will be enlarged and real.
3. If the object is between the focus F1 ​ and the optical center O: The image will be formed on the same side as the object, and it will be virtual, not real.
4. If the object is at 2F1 ​: The image will be formed at 2F2​, and it will be of the same size as the object.
So, to get an enlarged real inverted image beyond 2F2​, one should place the object between F1 and 2F1​.
The correct answer is (b) Between F1F_1F1​ and 2F12F_12F1​.
