A small telescope has an objective terms of focal length $144\;cm$ and an eye -piece of focal length $6.0\;cm$ . What is the magnifying power of the telescope ?What is the seperation between the objective and the eyepiece ?

Question

$\begin{array}{1 1} M.P=24; seperation=150\;cm \\ M.P=-24; seperation=150\;cm \\ M.P=25; seperation=151\;cm \\ M.P=-25; seperation=151\;cm \end{array} $
