1.	A telescope consisting of an objective of focal length 60cm and a single eye lens of focal length 15cm is focused on a distant object in such a way that parallel rays comes out from the eye lens. If the object subtends an angle 2° at the objective, the angular width of the image.
Answer» s of focal length 5 cm is focussed on a distant object in such a way that parallel rays COMES out from the eye lens. If the object subtends an angle 2∘ at the OBJECTIVE, the angular WIDTH of the image Magnification m=f0/fe ALSO m=Angle subtanded by the imageAngle SUBTENDED by the object ∴f0/fe=α/β⇒α=f0×βfe =60×25 =24∘
