Answer 2

Explanation:

Given,

object height(h)=5cm

object distance= -25cm

focal length=15cm

By using the mirror formula we can find the image distance(v):-

1/v+1/u=1/f

1/v-1/25=1/15

1/v=1/15+1/25

1/v=8/75

Therefore, v=75/8≈9.75cm

Also, Magnification=Height of image/ height of object = -(image distance/object distance)

so, h/5=-(75/8/-(25))

h/5=75/8*25

h=15/8≈1.8cm

Hence, i).Image distance=9.37cm

ii).Image height=1.8cm

Therfore, Image is Virtual,Erect and Diminished
