उत्तर
Distance of the object from plane mirror = 2 cm
If object is moved by 1 cm towards the mirror, then distance between the object and plane mirror = u = 1 cm
We know in case of plane mirror,
Distance of object from plane mirror = Distance of the image of the object from plane mirror
⇒ v = u = 1 cm
∴ Distance between its object and new image = u + v = 1 + 1 = 2 cm
