Solution Verified by Toppr

Correct option is B)

Focal length  f=−40cm (-ve sign appears because the mirror is concave)

Object distance  u=−60cm

Magnification(m)=?

Using mirror formula

f 1 ​ = v 1 ​ + u 1 ​ 40 −1 ​ = v 1 ​ + 60 −1 ​ v 1 ​ = 120 −3+2 ​ v=−120cm Magnification m= u −v ​ = −60 120 ​

=−2     (The minus sign signifies that the image is inverted)
