Answers

Answered by madaboutgirls

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

madaboutgirls: ok

madaboutgirls: 1/14 +1/v=1/f

madaboutgirls: this will give you 35

madaboutgirls: position of image

madaboutgirls: then I put the values in magnification formula
