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
