(2006)​

Answer 1

by magnification formula answer should be 48cm

Answer 2

Answer:

use magnification formula of

hi/h○= -V/U

where hi height of image

h○ height of object

V image distance

U object distance

HERE, it is given that U= -12 (-ve because object is real)

hi/ho=4/1

-V/U=4/1

-V/-12=4/1

V=12×4=48

HENCE, V=48 cm

nature of image = Virtual,large in size and erecte
