Manjula is observing her image in a plane mirror. The distance between herself and the mirror is 5 m. She moves 1 m towards the mirror. The distance between herself and her image now is
A.1 m
B.4 m
C.8 m✓ Correct
D.10 m
Explanation
In a plane mirror, the image is formed as far behind the mirror as the object is in front. After moving 1 m towards the mirror, Manjula is 4 m from the mirror, and her image is also 4 m behind the mirror. So the distance between her and her image is 4 + 4 = 8 m.
