Answer:
+ 6 cm
Explanation:
Given :
Object distance = - 10 cm
Focal length = + 15 cm
We have to find image distance.
We know :
1 / f = 1 / v + 1 / u
1 / v = 1 / f - 1 / u
1 / v = 1 / 15 + 1 / 10
1 / v = 1 / 6
v = + 6 cm
Hence .image distance is 6 cm from the mirror behind it.
The image is erect and virtual.
