Question

i want you to solve the following questions

Answer 1

Ans1) height of object : +4 cm

Object distance : -24 cm

Focal length : -12 cm

By mirror formula

1/v + 1/u = 1/f

1/v +1/-24 =1/-12

By solving,

V = -24

Image distance is 24 cm

Image is at c

Magnification = -v/u

= -(-24)/-24

=-1
