Ray Optics

The size of the image of an object, which is at infinity, as formed by a convex lens of focal length \(30 \mathrm{~cm}\) is \(2 \mathrm{~cm}\). If a concave lens of focal length \(20 \mathrm{~cm}\) is placed between the convex lens and the image at a distance of \(26 \mathrm{~cm}\) from the lens, the new size of the image is
