Answer 1

Answer:

.

Explanation:

Answer 2

Answer:

(i) The diagram is shown here.

(ii) The position of the images will be more than twice the focal length of lens.

(iii) The image will be magnified, real and inverted.

(iv) As the object move towards F 1

the image will shift away from F 2

and it is magnified. At F 1

the image will form at infinity and it is highly magnified.

Between F 1

and optical centre, the image will form on the same side of object and will be magnified.
