The image formed by a convex mirror is always virtual and located behind the mirror. Using the mirror formula, 1/f = 1/v + 1/u, and given that the image distance (v) is 5 cm when the object distance (u) is 10 cm, we can find the focal length (f) and then calculate the new image distance when the object is 5 cm away. The image will be 2.5 cm behind the mirror.
