    The image formed by the mirror will still be inverted and equal in size to the object when it was 20 cm away from the mirror. This is because the image distance (i) is dependent on the object distance (o) and the focal length of the mirror (f). In this case, the mirror is likely a concave mirror with a focal length of 10 cm (half of the object distance when it was 20 cm away). Therefore, when the object is moved to a distance of 5 cm away from the mirror, the image distance can be calculated using the equation: 1/i = 1/f - 1/o. Plugging in the values, we get 1/i = 1/10 - 1/5, which simplifies to i = -10 cm. The negative sign indicates an inverted image, and the value of -10 cm is equal in magnitude to the object distance when it was 20 cm away from the mirror. Therefore, the image will be inverted and the same size as the object, located 10 cm behind the mirror.
