​

Answer 1

Answer:

Distance between herself and her image = 8 m

Explanation:

We know that,

In a Plane Mirror,

Distance of object from mirror = Distance of image from mirror

Now, according to the Question,

Distance of Manjula from mirror = 5m

then, she moves 1 m towards the mirror,

Thus,

Distance of Manjula from mirror = 5 - 1 = 4 m

Hence,

Distance of image of Manjula from mirror = 4 m

∴ Distance between image and object = Distance of Manjula from mirror + Distance of image of Manjula from mirror

∴ Distance between herself and her image = 4 + 4

= 8m

Thus,

Distance between herself and her image = 8 m
