Answer:
A boy is standing 8 m in front of a mirror. He moves 3 m towards the mirror. What will be the distance between a boy and his image now? *
Explanation:
From physics its 6 meters.
v=u , for plane mirror
(v = distance of image from the mirror)
(u= distance of object from the mirror)
Total distance between the image and object = v+u = 2u
here u= 3m
therefore distance = 6m
