Question

Kanchi is observing her image in a plane mirror the distance between the mirror and image is 5m if she moves 2 metre towards the mirror then the distance between Kashi and her image will be

Answer 1

6m. As kanchi was originally 5m away from the mirror(because the distance of image from the mirror is same as that of the object from the mirror).2m towards the mirror reduces the distance to 3m and so the final distance between kanchi and her image is 3+3=6m.
