Solution

Magnification produced by a spherical mirror is given by the relation,

`m=`

`m=h_1/h_0=-u/v`

Let the height of the object, `h_0=h`

Then, height of the image, `h_1=-3h`(image formed is real)

`-3h/h=-v/u`

`v/u=3`

Object distance, u= – 10 cm
= 3 × ( – 10) = – 30 cm
Here, the negative sign indicates that an inverted image is formed at a distance of
30 cm in front of the given concave mirror.
