An object is placed 20,0 cm in front of a convex mirror. The image is formed 10,0 cm behind the mirror. A second object, twice the size of the first object, is also placed in front of the mirror but at a different position. The image of the second object is the same size as the image of the first object. How far in front of the mirror was the second object placed, i.e. what is the object distance of the second object?
