Answer 2

Answer:

14cm

Explanation:

1) the distance from the mirror is 10cm

2) now the object is shifted 3 cm towards the mirror so the distance is (10-3)cm = 7cm

3) in a plane mirror the image is formed exactly at the same distance of the object from the mirror but is formed behind the mirror.

4) so the image is formed 7 cm away from the mirror but behind the mirror.

5) so the distance between the object and the mirror is (7+7) cm = 14cm.

Hope it helped
