To obtain a magnification of, –0.5 with a convex lens, the object should be placed:(a) at F (b) between optical centre and F(c) between F and 2F (d) beyond 2F
(d) Beyond 2F
Explanation
Since, the magnification of the image is negative, it means the nature of the image is real and inverted. Also, size of the image is less than 1 which is 0.5, it implies that the size of the image is diminished.
Thus, the image of this nature and size is formed when the object is placed beyond $2F$ of a convex lens.
