Question

You are standing 8metre away from the mirror placed in front of you and your mom is standing 3m behind you. What will be the distance between you and yours mother image of you move 3m towards the mirror​

Answer 1

Answer:

Image -object distance=distance between obj and mirror+distance between image and mirror.

For plane mirrors object and image distances are always equal.

Man is standing at 12 m. So the image forms at 24 m away from him.

He wants to be 5 m away from his image i.e.,

Object distance + image distannce=5

Let object distance=image distance=x

2x=5 =》x=2.5

He should be at 2.5 m away from mirror in order to form image 5 m away from him.

He should walk=12-2.5=9.5 m
