Solution
The image of an object placed at a long distance in front of a convex mirror is formed at principal focus. The radius of the curvature of convex mirror is 20 cm.
The focal length of the convex mirror = radius of curvature/2.
Focal length of convex mirror = 20/2 = 10 cm.
So the image will form at a principal focus 10 cm away from the pole.
