image formed.
please explain your answer and I will mark you brainliest ​

Answer 1

Explanation:

f = -12cm

u = - 6cm

ho= 8cm

1/v + 1/u = 1/f

1/v = 1/-12 + 1/6

= -1 + 2

12

= 1/12

v = 12cm

m = -v = hi

u ho

hi = -12 x 8

-6

hi= 16cm

Answer 2

We know that, 1/v + 1/u = 1/f u = - 15 cmFocal length = - 10 cm 1/v = 1/-10 - 1/( - 15) 1/v = 1/-10 + 1/15 = -3 + 2/30 = - 1/30 v = - 30 cm
