The magnification of an image formed by a lens is −1. If the distance between the object and its
image is 60 cm, what is the distance of the object from the optical centre of the lens? Find the
nature and focal length of the lens. If the object is displaced 20 cm towards the optical centre of
the lens, where would the image be formed and what would be its nature? Draw a ray diagram to
justify your answer.

Thanks for the answer, pratyush
my pleasure
You are telling that, when we place a object between O & F, the image will form at infinity, i think that statement is wrong
but I think it's correct
No it's wrong

Pratyush89's answer is correct, except: When displaced 20cm towards the optical centre the image would be formed on the same side of the lens and it would be virtual and erect.
