Answer 2

It is given that,

Height of the object, h = 5 cm

Object distance, u = -20 cm

Height of the object, h' = 10 cm

Magnification of the mirror,  

v = 40 cm

So, the image is formed behind the mirror at a distance of 40 cm. The mirror is concave mirror.

Using mirror's equation :

f = -40 cm
