Problem
A real object is kept in front of a lens in air. The object is a linear extended object with its length perpendicular to the optical axis of lens. With reference to different cases of image formation by lens, choose the correct options:
(A) If the image has a magnification −2.5 then Image is real and power of lens is positive.
(B) If the magnification of the image is +0.5 then Image is virtual and power of lens is negative.
(C) If length of image is the same as that of object then Image is real and power of lens is positive.
(D) If length of image is the same as that of object then Image is virtual and power of lens is negative.
