Answer 1

Answer:

mirror name- convex

focal length=15cm

height of image= 1/3h

height of the object=h

now ,

m= height of image/height of OBJ=(-v)/u

1/3h/h= -v/u

1/3=-v/u

u=-3v

now

by mirror formula

1/f=1/v+1/u

1/15=1/v+1/u

1/v=1/15 -1/u

1/v=1/15+1/3v

1/v=v+5/15v

15=v+5

v=10

so object post

u=-3v

u=-30
