Explanation:

height of object (h1):. 1cm

height of image (h2): -1.5cm

object distance (u): -15cm

1. To find the position of the image we need to find v

so,

h2/h1= -v/u

-1.5/1 = -v/-15 (cross multiplication)

-22.5=v

2. To find focal lenght

1/f = 1/v+1/u

1/f= 1/-22.5+1/-15

f= -9

hope you like the answer mark it as brilliant
