• # question_answer An object $5cm$ tall is placed $1m$ from a concave spherical mirror which has a radius of curvature of $20cm$ The size of the image is                                                             [MP PET 1993] A)            $0.11cm$                             B)            $0.50cm$ C)            $0.55cm$                             D)            $0.60cm$

$\frac{I}{O}=\frac{f}{(f-u)}\Rightarrow \frac{I}{+5}=\frac{-10}{-10-(-100)}\Rightarrow I=0.55\ cm$
