Answer 1

(i) (a) The lens used here is a concave lens.
(b) The image is diminished.

(ii) No, concave lens cannot form an image of size two times that of the object because it diverges the rays incident on it and only produces a diminished image. The image formed by a concave lens is virtual and diminished.
