A toy of height 10 cm is kept 18 cm away from a convex mirror. The convex mirror has a focal length of 12cm. At what distance will the image of the toy be formed?

HERE IS YOUR ANSWER

M = H2 = -V/U = 1/2

= -V = U/2

V = -4/2

1/V + 1/U = 1/F

1/-U/2 + 1/U = 1/18

-2/U + 1/U = 1/18

-U/U = 1/18

U = -18

U = 18
