In displacement method, the distance between object and screen is \( 96 \mathrm{~cm} \). The ratio of length of two images formed by a convex lens placed between them is 4.84 .
(a) Ratio of the length of object to the length of shorter image is \( 11 / 5 \)
(b) Distance between the two positions of the lens is \( 36 \mathrm{~cm} \)
(c) Focal length of the lens is \( 22.5 \mathrm{~cm} \)
(d) Distance of the lens from the shorter image is \( 30 \mathrm{~cm} \)
