Where should an object be placed in front of the same convex lens to obtain the same real image the same size the same object?
Solution
✅ Correct Option: 4
For a convex lens, an object placed at the centre of curvature, that is at , forms a real, inverted image of the same size at on the other side. At infinity the image is a point at the focus, at the focus the rays emerge parallel, and inside the focus the image is virtual and magnified.
Note: The NTA wording repeats 'the same' and omits linking words. We have read it as asking for a real image equal in size to the object.
