Explanation / Answer

object distance, u=17cm

radius of curvature of concave spherical mirror, R=24cm

height of the object, h=0.55 cm

a)

use,

1/u+/v=2/R

1/17+1/v=2/24

===> v=40.8 cm

position of the image, v=40.8cm

b)

magneficaion, m=v/u=h'/h

====> m=40.8/17=h'/0.55

40.8/17=h'/0.55

===> h'=1.32 cm

c)

iamge is inverted

d)

nature of the image is real
