Answer 2

Answer:

Option A

Explanation:

As we know that the image formed in a plane mirror is at same distance from the mirror as the object is standing.

So let's initial distance between Ritu and mirror is x.

Distance between Ritu and her image =2x

2x =10

x=5m

when Ritu moves 2m forward then the distance between Ritu and mirror is 3m.

so distance between Ritu and her image is 2x3=6m.
