A convex lens of focal length 20 cm can produce a magnified virtual as well as real image. Is this a correct statement ? If yes, where shall the object be placed in each case for obtaining these images ?
Yes, the statement is correct.
For magnified virtual image : The object should be placed between optic centre © and focus (F) (< 20).
For magnified real image : Placed between focus (F) and centre of curvature (2F) (20 - 40).
