Explanation / Answer

(A) m = -di /do

-3.4 = - di / do

di = 3.4do

Applying 1/f = 1/di + 1/do

1/2.5 = 1/3.4do + 1/do

1/2.5 = 1.294 / do

do = 3.235 mm ............Object distance

(B) for eyepiece,

1/f = 1/di2 + 1/do2

1/10 = 1/4do2 + 1/do2

do2 = 12.5 cm

from (A) di = 3.4 x 3.235 = 11 mm

distance between them = di + do2

= 13.6 cm
