1.	The focal length of the objectives and the eyepiece of an astronomical telescope are `16cm`and`2cm` respectively .A planet is viewed with its help ,thenA. The angular magnification of the planet is`-800`B. The image of the planet is invertedC. the distance between the objectives and the eye piece of`16.02`D. All the above
Answer» Correct Answer - 4 `therefore` Distance between objectives and eyepiece `=f_(0)+f_(e)=16.02m` Angular magnification`M=-(f_(0))/(f_(e))` or`M=(-16)/(0.02)=-800` The image formed by a telescope is always inverted.
