Answer» Focal length of a concave mirror is $- 20 c m$ . Match the object distance(Real object) given in column $I I$ corresponding to magnification (only magnitude) given in column $I$ . $\begin{matrix} Column I & Column II (A) 2 & (p) 10 c m (B) \frac{1}{2} & (q) 30 c m (C) 1 & (r) 20 c m (D) \frac{1}{4} & (s) none of these \end{matrix}$
