A) Convex mirror of radius of curvature \[12cm\]
B) Concave mirror of radius of curvature \[12cm\]
C) Concave mirror of radius of curvature \[4cm\]
D) Plane mirror of height \[12cm\]
Correct Answer: B
Solution :
Erect and enlarged image can produced by concave mirror. \[\frac{I}{O}=\frac{f}{f-u}\Rightarrow \frac{+\ 3}{+1}=\frac{f}{f-(-\ 4)}\Rightarrow f=-\ 6\,cm\] \[\Rightarrow R=2f=-\,12\,cm\]You need to login to perform this action.
