Focal length of the objective lens, = 15 m =cm
Focal length of the eyepiece, = 1.0 cm
(a) The angular magnification of a telescope is given as:
15/1
Hence, the angular magnification of the given refracting telescope is 15
Focal length of the eyepiece, = 1.0 cm

Hey !!
| em / m | = | f₀ / fe |
f₀ = Focal length of objective
fe = Focal length of eyepiece
| m | = 15 × 100 / 1 = 1500
∵ image formed is inverted
∵ Angular magnification = + 1500
Good luck !!
