the distancce between image and mirror is same as the distancce between the object and mirror.
SO when object is moved 2 cm towards the mirror, the new distance between the object and miorror will be 3cm
and thus the distance between the image and mirror wil also be 3 cm
thus, since the object and image are exactly opposite to each other with respect to mirror so the distance between them will be 6cm
