Answer:
An object placed in front of a plane mirror appears to be at the same distance behind the plane mirror.
The distance of the object from the mirror surface = 2 m + 50 cm = 2m + 1/2m = 2.5m
The man is 2 metre away from the mirror .
The distance between the eye of the person and the image of the object formed in the mirror = (2+2.5) m = 4.5m. (Ans)
