. An astronomical telescope has an angular magnification of magnitude 5 for distance objects. The separation between the objective and the eye piece is

(a) f_o = 45 cm and f_e = –9 cm

(b) f_a = 50 cm and f_e = 10 cm

(c) f_o = 7.2 cm and f_e = 5 cm

(d) f_o = 30 cm and f_e = 6 cm

Best Answer

Image formed by objective (I₁) is at second focus of it because objective is focused for distance objects. Therefore,
