  1. Answer:

    Object distance u=−36 cm

    Focal length of concave mirror f=−12 cm

    Using mirror formula :

    v

    1

    +

    u

    1

    =

    f

    1

    Or

    v

    1

    +

    −36

    1

    =

    −12

    1

    ⟹ v=−18 cm

    Magnification

    h

    o

    h

    i

    =

    u

    −v

    Or

    10

    h

    i

    =

    −10

    −(−18)

    ⟹ h

    i

    =−18 cm
