Explanation / Answer

a) Apply, 1/do1 + 1/di1 =1/f1

1/di1 = 1/f1 - 1/do1

1/di1 = 1/7.5 - 1/14.1

di1 = 16 cm

b)
magnification, m1 = -di1/do1

= -16/14.1

= -1.136

c) object distance for the seond lense, di2 = 31 - 16

= 15 cm

d) Apply, 1/do2 + 1/di2 =1/f2

1/di2 = 1/f2 - 1/do2

1/di2 = 1/7.5 - 1/15

di2 = 15 cm

e) magnification, m2 = -di2/do2

= -15/15

= -1
