# Image of an object at infinity is formed by a convex lens of focal length 30 cm such that the size of the image is 2 cm. If a concave lens of focal length 20 cm is placed in between the convex lens and the image, at a distance 26 cm, from the convex lens size of the new image is

$\begin {array} {1 1} (1)\;2.5\: cm & \quad (2)\;2.0\: cm \\ (3)\;1.025\: cm & \quad (4)\;1.05\: cm \end {array}$

(1) 2.5 cm
