(A) For a convex mirror,the radius of curvature $R = 10\,cm$. The focal length $f = R/2 = 5\,cm$.For a real object placed at a distance $u$ (where $u Since $f = 5\,cm$,we have $1/v = 1/5 - 1/u$.As the object distance $u$ varies from $-\infty$ to $0$,the image distance $v$ varies from $0$ to $f$.Specifically,as $u 	o -\infty$,$v 	o 0$,and as $u 	o 0$,$v 	o 0$. The maximum value of $v$ occurs as the object approaches the pole,where $v$ approaches $f = 5\,cm$.Therefore,the image is always formed between the pole $P$ and the focus $F$,and its distance from the mirror cannot exceed the focal length $5\,cm$.

What can be the largest distance of an image of a real object from a convex mirror of radius of curvature $10\,cm$?

Assertion : The formula connecting $u, v$ and $f$ for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature.
Reason : Laws of reflection are strictly valid for plane surfaces,but not for large spherical surfaces.
