`F_(1) and F_(2)` are focal length of objective and eyepiece respectively of the telescope. The angular magnification for the given telescope is equal to

Options

A. `(F_(1))/(F_(2))`
B. `(F_(2))/(F_(1))`
C. `(F_(1)F_(2))/(F_(1) + F_(2))`
D. `(F_(1) + F_(2))/(F_(1)F_(2))`

Answer

A, B

Explanation

In normal adjustment of the telescope, `|m| = (f_(0))/(f_(e)) = (F_(1))/(F_(2))`
