Answer:
20 cm
explanation:-
The correct answer is 20 cm behind the mirror. As we can see from the image, the image formed by the plane mirror is at the same distance behind the mirror as the object is in front of the mirror. So the image will be formed behind the mirror at the distance = Distance of object from the mirror (front) = 20 cm.
