the position of the image is 35 cm behind the mirror the length of the image will be 5 cm
by the mirror formula
1\v+1\u=1/f
this will give you the distance of the image
then by magnification formula you can find the length of image
dim/dob=lim/lob

ok
1/14 +1/v=1/f
this will give you 35
position of image
then I put the values in magnification formula
14/35=2/x
then x is 5cm image size
image distance is 35cm
now thank me
