Answer 2

Answer:

In a plane mirror, the image is as far behind the mirror as the object is in front of it.

Since the image of the object is 4 m behind the plane mirror, the object is 4 m in front of it.

When the object moves one metre towards the mirror, the object is now at a distance of 3 m in front of the mirror.

The image therefore would be formed 3 metre behind the mirror. And the distance between the object and its image would be 6 m.
